Valve Index Review – The Enthusiast’s Choice in VR Headsets

The Valve Index headset is costlier and fewer user-friendly than its nearest competitor, the Oculus Rift S, however the expertise it gives is the clear selection for VR fanatics who need to maximize immersion. Learn on for our full Valve Index evaluate to study if this headset is for you.

As standard, we’ll begin up prime with a high degree evaluation abstract followed up with an in-depth evaluate further down. [Note: this review is an expansion and refinement of our previous in-depth preview, so some of the text may be familiar].

Valve’s Index headset asks for a premium worth and manages to ship a premium experience. From the a hardware standpoint, the headset feels very nicely constructed and I find it to be probably the most snug headset presently obtainable. That’s because of its thoughtful ergonomic design which presents a wide range of adjustments (together with hardware IPD and lens-to-eye changes) as well as spring-loaded aspect struts which let you placed on and remove the headset with out tightening and loosening it every time.

Though it has the same 1,440 × 1,600 per-eye decision because the Vive Professional, the move to LCD displays with RGB subpixels presents higher fill issue and a bit much less screen-door effect. In comparison with the unique Vive and Rift (both with 1,080 × 1,200 per-eye OLED shows), it’s a big discount in the screen-door impact, however nonetheless seen at occasions.

LCD means worse black ranges, so darker scenes have a greyish, low-contrast look in comparison with the wealthy blacks seen in OLED headsets. I haven’t been capable of spot any ghosting from the Index’s display (which is extra widespread with OLED displays).

Index supports 80Hz, 90Hz, 120Hz, and 144Hz refresh rates. Most PC headsets run at 90Hz which seems and feels high quality, but there’s a particular immersive benefit to going larger. With 144Hz on Index, the whole lot just feels smoother and monitoring even feels tighter (as a result of latency is lower and tracked objects transfer more easily). Nevertheless, to get probably the most out of the higher refresh charges, you’ll need to pair Index with a very high-end GPU (like an RTX 2080 Ti) and CPU, otherwise you could need to show down the headset’s decision to take care of high body rates with out continuous use of reprojection or motion smoothing.

Between its decision, lenses, high refresh rates, and ultra low persistence, Index is the leader in visible clarity over pretty much any headset besides (arguably) the HP Reverb, which gives far more resolving energy because of 2,160 × 2,160 per-eye decision concentrated over a smaller area of view (but is somewhat compromised by more than ideally suited mura).

Index gives the widest area of view than different headsets in its class, at around 120 or 130 degrees. That is because of larger lenses, but in addition a dial on the aspect of the headset that permits you to deliver the lenses very near your eyes, which allows extra customers to experience the optimum subject of view. The enchancment doesn’t feel like an evening and day distinction at first (like it does with the ultra-wide FOV Pimax headsets), but going back to other headsets makes it fairly noticeable and you’ll be wishing you have been again in Index.

The larger area of view additionally brings with it a bigger sweet spot, which suggests the image sharpness doesn’t fall off as fast as you look towards the sides of the lens. The Vive headsets have a notoriously small candy spot, and Index gives a pleasant improvement by comparison. As with all headset, dialing in the match to get your eye to the center of the candy spot is necessary for max clarity.

Unfortunately the brand new lens design brings fairly a bit of glare with it, which illuminates the sides of the lens when there’s brilliant objects towards darker backgrounds. At occasions this may be as dangerous if not a bit of bit worse than the original Vive, but as with just about any headset, you gained’t see it until you’re taking a look at one thing excessive distinction. The glare appears to concentrate towards the sides of the lens and you may scale back it somewhat by dialing back the sector of view a bit.

The headphones on Index are simply wonderful; simply the most effective of any headset available on the market. The floating design is sensible in the best way that the headphones don’t contact your ears at all, but still supply large audio high quality with a lot of power, deep bass, and a full audio profile. Compared to the Rift S (which has notoriously dangerous audio high quality), it’s really a night and day difference. Index additionally presents higher sound than the Vive Professional and the unique Rift (which was the audio quality leader, till Index).

The Valve Index controllers are a pleasant upgrade (finally) from the Vive wands because of the addition of a thumbstick and face buttons, in addition to a more intuitive ‘grab’ enter in the type of a force-sensitive handle.

It may be troublesome to find a good match around you hand with the ‘cinch’ design, however the controller works properly when you do, allowing you to naturally clasp the deal with to initiate a ‘grab’, or launch it utterly to launch your seize. On the prime of the cinch there’s a bit metallic piece which might be moved between four positions to make the cinch better fit totally different hand sizes but it might get in the best way of reaching your thumb to the thumbstick and face buttons.

Index can monitor the position of all your fingers, which is fascinating, but frankly doesn’t seem so as to add much to the experience. There’s the novelty period of taking a look at your fingers move for the primary two minutes of using the controllers, however past that, there’s few significant interactions that really come from it. On the surface it looks like independently tracked fingers means you’d all of the sudden be capable of intuitively work together with the virtual world utilizing high quality finger manipulations, but the actuality is that this isn’t actually attainable with the restrictions of this type of finger tracking. Until Valve’s upcoming VR recreation (or some other artistic developer) exhibits that this finger tracking tech is actually compelling for gameplay, my gut says it may need been higher to scrap the additional tracked fingers in favor of a controller that’s smaller, lighter, and cheaper, with a more concentrated middle of gravity

While headsets like the Rift S are shifting toward a more user-friendly strategy by adopting inside-out tracking, Index continues to be reliant on the same external tracker paradigm as before. Meaning you’ll need a dedicated playspace with room to completely or semi-permanently mount beacons for tracking. This makes for a longer and more complicated preliminary setup course of, however means strong and performant tracking in the top.

SteamVR (the element of Steam which is required for using Index) still seems like a power-user’s utility fairly than an inviting portal into virtual actuality. I’m a hardcore PC gamer who has been utilizing VR for years now, and I still find some of SteamVR’s settings confusingly organized and interconnected. Much of the options are simply not explained in any meaningful means, and novice users might easily degrade their expertise by by accident hitting a mistaken verify field. SteamVR continues to be finicky at occasions and can sometimes check your troubleshooting expertise.

Despite having two respectable cameras on the front of Index, Valve is presently doing virtually nothing with them. You’ll be able to double-press the system button to look via the cameras, nevertheless it takes far too lengthy for the view to seem for it to be any use for shortly peering outdoors of the headset. Valve has teased some stylized pass-through modes previously, however it seems they’re still treating the cameras as a improvement toy as an alternative of a proper function of the headset.

Against this, the pass-through view on the Rift S is used to make establishing the play boundaries simpler (by wanting by means of the passthrough view and tracing the play space) and in addition makes onboarding easier as a result of you’ll be able to look via the cameras to easily decide up your controllers after you put on the headset (which is far nicer than feeling around for the controllers and putting them on blindly). Valve really ought to steal these ideas to make Index a bit much less cumbersome in the initial setup and onboarding.

The full Index package runs $1,000 and comes with all of 2016’s VR caveats: set up everlasting or semi-permanent monitoring gear, work out the right way to use fiddly SteamVR software program and settings, and discover ways to dial in all the headset’s adjustments. Not to mention that to get probably the most out of the 144Hz succesful headset, you’ll need enthusiast grade PC hardware to match.

On this sense, I liken the Index strategy to a DSLR digital camera—costlier, however capable of taking great pictures so long as you set in the time to study the ins and outs, and have applicable hardware to help it (like a very good tripod and lens).

Oculus however is aiming extra for the ‘point-and-shoot’ digital camera strategy with Rift S—decrease value, less complexity, and extra consumer friendly—however merely not able to attaining the same degree of constancy.

For that purpose, Index is a superb selection for fanatics, but not an ideal selection for novice users or those who discover themselves not diving into VR fairly often because of the friction of use.

Right here’s what you want set up (plus a PC) to make use of the Rift S (left) and Index (right). | Photograph by Street to VR

When you’ve got a first-gen VR headset and discover you aren’t utilizing it fairly often, think about that ease-of-use (and not things like resolution, subject of view, and refresh fee) is perhaps the rationale why—in that case, Index isn’t more likely to make you employ VR any greater than you’re at present. Then again, when you’re a diligent enthusiast who makes use of VR a lot already with a first-gen headset, Index will possible be an excellent upgrade to your expertise.

In fact, a headset is nothing without content. Index is suitable with all SteamVR content material, and while the controllers work nice for present apps with legacy input bindings, developers might want to update their video games if they need to make specific use of the controller’s new features. Hopefully Valve’s upcoming VR recreation will come along and present what the controllers are really capable of, but they still haven’t introduced a release date for the game, not to mention even given it a name.

Previously, choosing a SteamVR headset over an Oculus headset primarily meant being locked out from enjoying Oculus exclusive content material; although it’s been technically attainable to play Oculus video games by means of the unofficial ‘Revive’ mod, the previous Vive wands have been a poor stand-in for the Touch controllers and made it a compromised experience. The Index controllers however seem to work a lot better for this objective, making Oculus unique content material lastly feel really playable on headsets like Index. And while that opens the exciting risk of enjoying a few of the greatest VR content from Oculus, it’s a bit of a raffle contemplating Oculus might break help for Revive at any time.

For my head, Index is the brand new bar for headset comfort, surpassing the Vive Pro. For just about any headset, long periods imply often making small changes to take care of consolation; with Index it seems like I want less little adjustments over lengthy periods than with other headsets.

Ergonomics in VR headsets isn’t just about comfort though, it’s additionally about visible readability, since getting your eyes properly aligned with the lenses can make the difference between a sharp and cozy image, or a blurry one with eyestrain. Without with the ability to get your eyes comfortably into preferrred alignment, just about every visual facet of the headset might be compromised.

Fortunately, Index has a physical IPD adjustment, which ranges from 58mm to 70mm, accommodating the overwhelming majority of users. On prime of that, the knob on the appropriate aspect of the headset enables you to convey the lenses very close to your eyes, maximizing the sector of view and your capacity to align with the lenses’ sweet spot. The Vive Professional has an analogous lens-to-eye distance adjustment nevertheless it doesn’t allow you to get the lenses as shut as Index.

The IPD adjustment is on the bottom of the headset. A digital indicator in the headset specifies the current setting right down to the tenth of a millimeter. Compared to the IPD dial on the Vive and Vive Pro, it’s somewhat more durable to dial in such a exact worth, but straightforward sufficient to get right down to the fitting millimeter. | Photograph by Street to VR

From a comfort standpoint, Index’s padding is smooth and cozy; a knob on the again of the head-mount permits you to finely regulate the tightness of the head-mount, and the visor rotates concerning the hinges to find a good resting place towards your face. Although it’s effective for me, I don’t anticipate that the face gasket will fit everyone completely (it’s extremely comparable in geometry to that of the original Oculus Rift, so when you’ve got experience with that headset you’ll know what to expect). Skinny-framed glasses ought to suit inside okay, and the lens-to-eye adjustment knob will make it straightforward to make space for them in the course of the lenses.

In case it doesn’t fit everyone properly, the face gasket is magnetically hooked up and easily detachable; Valve says it plans to release CAD information to make it straightforward for third parties to make accessories for Index, which can hopefully mean available aftermarket decisions.

While the padding is pleasant towards the pores and skin, it appears to be a masking of types over prime of some underlying foam. As someone who performs an excellent bit of Beat Saber (which suggests sweating into the headset’s padding), the padding appears to need to hold onto moisture greater than with different headsets which use foam with no masking. The capability to easily remove the magnetic face gasket is really nice for pulling it out for a quick cleaning after a sweaty session, but those planning frequent workouts in their headset might need to hold an eye fixed out for a fitness-focused aftermarket gasket.

Index’s aspect struts are ‘springy’, identical to the unique Rift. Because of this there’s some ‘play’ to the fit, such you could put the headset on and take it off ‘hat style’ (back to front) without re-adjusting the tightening knob in the again each time. For probably the most part, that signifies that when you dial in the match of Index, you shouldn’t need to fiddle with it typically. That’s a pleasant enchancment over headsets like Rift S and Vive Professional, which usually have to be tightened each time you set them on after which loosened before being taken off.

Area of View

Because of Index’s ergonomic design, it’s straightforward to get your eyes right into the sweet spot of the lenses for the most effective visuals. This matters not just for readability, but definitely for subject of view too. Between the displays and the power to deliver the lenses very close to your eyes, Valve says they anticipate that the majority users will get a subject of view that’s roughly 20 degrees wider than they’d see with a Vive. The distinction at first doesn’t appear large, but going again to headsets like the Vive and Rift S makes it abundantly clear that Index has the widest and most desirable FOV of the bunch.

It’s attainable to convey the lenses so close which you could start to see the sides of the displays in your peripheral vision. That is usually undesirable, but tolerable if you would like the utmost attainable FOV. In case you’d favor the tender spherical edges of the lenses as the restrict of your FOV as an alternative, it’s incredibly straightforward to dial the lenses again only a bit till you don’t see the show edges anymore.


With a resolution of 1,440 × 1,600 per-eye, Index uses an LCD show with RGB subpixels which are recognized for having better fill-factor/much less display door effect (SDE). It’s a notable reduction in SDE and improvement in resolution in comparison with the original Vive and Rift (both use OLED shows at 1,080 × 1,200 per-eye); SDE continues to be seen, but simply melts away in darker scenes and towards textures.

In comparison with the Vive Professional (1,440 × 1,600 per-eye OLED) nevertheless, there’s little general distinction in SDE. This is possible partly because of the bigger Index FOV (which serves to scale back pixel density compared to a smaller FOV), and the truth that RGB subpixels create a slightly more outlined (if smaller) SDE construction in comparison with the offset pattern seen with PenTile OLED displays.

Although the Rift S has a lower decision (1,280 × 1,440), its concentrated over a smaller subject of view than Index, making the sharpness/resolving of the headsets quite comparable.

Mura (inconsistencies in brightness and shade between pixels) is pretty minimal; it’s improved over the unique Vive, on par with the Vive Pro, and a bit more seen than the Rift S.

General readability on Index pulls forward of the Rift S and Vive Pro nevertheless, which is because of the super low persistence, excessive refresh rates, and lens differences. Index’s general readability even competes properly with HP’s Reverb headset, which has a lot greater resolution of 2,160 × 2,160 (and thus extra resolving energy) however fairly a little bit of mura, and may’t run at such high refresh charges or with such low persistence.

Refresh Price & Low Persistence

While most PC VR headsets have a 90Hz refresh fee (except the Rift S at 80Hz), Index is able to 80Hz, 90Hz, 120Hz, and 144Hz.

It’s exhausting to elucidate precisely how a better refresh fee makes the view by way of Index look extra immersive and strong, however it undoubtedly does. Although the 80Hz or 90Hz of different headsets is a lot snug and looks good, it’s still removed from the ‘perfectly smooth’ motion of actual life. At 144Hz, the whole lot just seems that rather more clean, adding to the ‘solidity’ of what’s round you. It in all probability also helps that a 144Hz refresh fee means lower latency too.

The high refresh fee works in conjunction with Index’s ultra low persistence to maintain the picture sharp even throughout motion. Persistence is how long a pixel stays lit, and in VR, decrease is best as a result of illuminating pixels for much less time reduces blur throughout head movement. All respectable headsets use low persistence, however Valve says that Index is the first headset to supply sub-pixel persistence, which in principle means nearly zero persistence blurring.

I might go thus far to say that the higher refresh price and extremely low persistence together are the greatest contributors to the increased immersion with Index, maybe much more so than the increase in subject of view.

Candy Spot

Index’s sweet spot (the world of the lens which gives the perfect readability) can also be noticeably improved over the Vive and Vive Pro. It’s not ‘edge to edge’ sharp whenever you rotate your eyes concerning the scene, however the sharpness doesn’t fall off almost as fast as with the Vives. The finish result is that it feels more natural to look across the scene together with your eyes somewhat than your head, compared to different headsets, which is particularly good considering the broader subject of view on Index.

God Rays & Glare

Photograph by Street to VR

For probably the most part, every part described above about Index’s visuals is either on par or an improvement over headsets in the identical class, but there’s one space the place Index makes a compromise: glare.

Whereas most different headsets use single-element lenses, Index makes use of dual-element lenses. I think this was executed specifically to broaden the sweet spot, however I additionally suspect it’s the rationale why glare has turn out to be extra obvious than other headsets just like the Rift S, Vive, and Vive Pro.

I need to be clear here because the terminology surrounding what many customers name ‘god rays’ and ‘glare’ isn’t notably precise—so I’m going to elucidate what I’m talking about with a bit of additional detail.

In terms of numerous light-related lens artifacts in VR headsets, there appears to be two main elements. The first is what I consider most people are speaking about once they say ‘god rays’—that may be the lens flare-like mild that appears to instantly emanate from shiny objects towards darker surroundings. God rays are the strains of sunshine you’ll be able to see coming instantly from objects in the scene. These strains are fairly defined, and sometimes level immediately towards or away from the very middle of the lens; you’ll be able to see them rotate around their host object as you progress your head. An excellent instance is white text on a black background—the text seems to flare in a quite discrete method, immediately towards and around the text.

Then there’s inner reflections, which usually equates to what some users call ‘glare’ (and that’s how I’ll confer with it right here). Glare is the broader mild scattering artifacts that don’t appear to emanate as immediately from the item in the best way that god rays do. Glare scatters around the area of view more globally than god rays.

With that in thoughts, on the subject of Index, god rays are an enchancment over Vive, and look to be about on par with the Rift S. However glare is worse than Rift S, Vive, and Vive Pro, and might be fairly obnoxious when you will have giant, high contrast parts towards darker backgrounds. The glare on Index appears to be brighter and more defined than with other headsets. It also tends to fall toward the outer edges of the sector of view, which I think makes it more noticeable due to the best way that our peripheral vision is extra sensitive to both movement and distinction than our central imaginative and prescient.

I suppose this was a essential concession to realize other goals in the lens design, however I’m stunned with how obvious the glare may be at occasions.

As ever, both god rays and glare go away in scenes with lower distinction. Sensible developers can mitigate god rays and glare by avoiding high contrast parts in their content material (Lone Echo being the premiere example)—and admittedly that might profit different headsets too if more builders have been cognizant of this; perhaps Index can be a very good wake-up call.

Black Ranges & Ghosting

As far as black ranges are involved, Index is on par with different headsets utilizing LCD displays just like the Rift S and Oculus Go. Many first-gen VR headsets (just like the Vive) used OLED shows which are capable of incredibly dark blacks, which look great in darker scenes, however could possibly be topic to ghosting. LCD may be vulnerable to ghosting too (in totally different circumstances), however I haven’t noticed any on Index.

Blacks in Index have that basic ‘LCD grey’ look to them, which makes for poor contrast in darker scenes in comparison with OLED. It’s not a deal breaker, but in case you play especially darkish video games like area sims and are used to OLED headsets, you’ll undoubtedly miss the wealthy blacks.

The floating headphones on Index are just flat-out wonderful. Whenever you put the headset on, you don’t even know they’re there because they don’t contact your ears. Then the audio comes in and growth—highly effective, full-bodied sound; easily the very best high quality built-in audio in any VR headset thus far. As these are technically audio system fairly than headphones, they’re going to be audible to different individuals in the room, but you’ll need to use them anyway. When you’d favor one other audio answer, you’ll be able to remove the Index headphones with an allen wrench and plug in your most popular headphones with the on-board three.5mm jack (hidden underneath the face gasket).

I’ve already written in-depth about Index’s headphones, though I’ll share an anecdote.

For me, a real ‘audio upgrade’ is when the improve lets you hear belongings you’ve never heard before in audio content that you simply’re intimately acquainted with. I’ve logged dozens of hours in The Lab through the years, however it wasn’t until I used to be using Index that I was struck by how intricate and detailed the sounds are from the little robot dog. It has a bunch of various animations, every accompanied by delicate noises that spotlight its movements. I wasn’t even specifically testing the headset’s audio, it was just one thing that caught my attention as the canine ran round me.

And that’s fairly freaking cool. The Lab came out in 2016—and I’ve explored rattling close to all of it—but three years later I experienced one thing that I never really observed till better hardware got here alongside and revealed it.

I spoke with a VR developer who had this similar expertise with Index of newly observed audio particulars, however in their very own software that they work on daily.

Index makes use of Valve’s SteamVR Monitoring tech, and supports each and a couple base stations. Monitoring feels as tight and strong as ever on Index. Particularly with the upper refresh price of the headset, monitoring makes actions in quick paced video games like Beat Saber feel barely easier to regulate.

With two base stations mounted at reverse corners of my playspace, I didn’t discover any occlusion points while I performed despite the front of the headset having many fewer tracking sensors than the Vive headsets.

Valve doesn’t advertise any particular efficiency enhancements from the 1.0 to the 2.0 base stations, although 2.0 can help bigger playspaces and up to 4 base stations for extra robustness to occlusion (although the latter advantages scarcely apply to in-home users). Certainly, I haven’t been capable of notice any tracking differences between the 1.0 and a couple base stations.

For many who ordered the Index full package (which includes two 2.0 base stations), you’ll additionally get some mounting hardware included. Every base station comes with a mounting bracket that can be screwed into the wall with included screws. The mounting brackets are also designed to take a seat on flat surfaces like a table or bookshelf for many who don’t need to screw them to the wall. The normal tripod screw on the bracket can fasten to the corresponding screw holes on the again or backside of the bottom stations, making both orientation work.

Valve calls the opening hiding beneath the magnetically hooked up face-plate the ‘frunk’. There’s a USB three.0 port in the aspect, and Valve envisions it as an enlargement port for individuals who need to experiment with adding numerous peripherals and add-ons to the headset. Valve says they haven’t any specific plans for the frunk. Until someone comes up with some extremely important add-on that matches in the frunk, it looks like a waste; with out it, Index presumably might have had a barely smaller footprint and less weight (particularly with removing the plastic faceplate and corresponding magnets).

Index Controllers (Knuckles)

Photograph by Street to VR

The Index controllers (formerly referred to as Knuckles) can work with any SteamVR headset, and eventually supply an improve over the Vive wand controllers.

From an input standpoint, the Index controllers are far more aligned with the Contact controllers by adding a trackpad, face buttons, and a much more pure grabbing enter because of the force-sensitive handle.

Knuckles is exclusive in two vital ways. To begin with, it’s ‘worn’ by tightening a cinch around your hand. This allows you to utterly ‘let go’ of the controller whereas it remains in your hand. The concept is that this can work with the force-sensitive deal with to allow for natural grabbing and releasing of digital objects by merely gripping or not gripping the deal with.

The second distinctive thing is unbiased finger tracking. The handle has embedded capacitive sensors which detect each of your fingers to animate your virtual hand to match. The trigger and all the face inputs (stick, trackpad, and buttons) are additionally capacitive, which suggests your entire hand place could be fairly successfully tracked and represented nearly.

Merely by having extra comprehensive inputs, a more natural gripping enter, and a more central middle of gravity, the Index controllers are an improve over the Vive wands. However the distinctive selling factors of the controller (unbiased finger tracking and the hand cinch) feel much less clearly useful.

It took some time to discover a respectable fit for the cinch. My initial instinct was to tug it tight and comfortable, however after about 15 minutes it started to feel uncomfortable so I needed to dial it back and find a stability between preserving it tight enough to maintain the controller on my hand however unfastened sufficient to remain snug. The method the cinch is tightened makes it straightforward to place extra strain on one aspect of your palm than the opposite. I found after tightening the controllers that I’d often have to regulate the position of the straps towards my hand to stop that pinching/strain sensation.

There’s a metallic piece that protrudes from the highest of the strap and might be moved into four totally different positions (by pushing it ‘into’ the controller after which rotating), which presents an necessary adjustment, however I additionally found that the metallic piece stands proud too far and easily will get a bit in the best way of reaching for the thumbstick and face buttons.

In the long run, the Index controllers may be snug, however you’ll have to spend a while really determining tips on how to make them suit you.

Then there’s the unbiased finger tracking, which up to now solely really matters for the primary two minutes of utilizing the controllers—you’ll stare at your shifting fingers and then move on to games which make no use of them. Yes, over time more games will add help to appropriately animate your fingers, but for all of the complexity this provides to the controllers it’s exhausting to imagine that that is a vital function. The expectation appears to be that it will make VR more immersive, but with none technique of lifelike manipulations of digital objects together with your fingers alone (which may’t be executed with out force-feedback), it actually doesn’t appear to be including much apart from those occasions where you need to stare at your fingers for the novelty of the fact that they’re tracked.

To not be underestimated nevertheless is the social presence that may seep in when users have extra outlined finger tracking. Although clearly an edge case, sign language customers may additionally discover Knuckles to be a step in the appropriate path in translating actual finger movements to VR.
