Our Take

Vive Cosmos

Vive Cosmos, by HTC, does not disappoint, however, failed to satisfy some of our experts’ hopes.

We went into the audit, figuring the Cosmos would undoubtedly get one of our experts’ top suggestions and effectively guarantee an honor; however, it wound up completing in the gathering with its genuinely unsuitable presentation.

This VR is uncommonly comfortable to understand and gives an exceptionally vivid encounter with regards to designs yet disillusioned us with its dull exhibition in our experts’ tests.

Likewise, it isn’t exceptionally comfortable to wear — especially if you have glasses on — and is somewhat more work to set up. It also requires some expensive extra equipment to run appropriately.

Valve Index

Valve’s Index is a premium VR set for enthusiasts: those of us who have an incredible PC, the space to set up outside sensors to cover a considerable territory, and who need to encounter the front line of hand-tracking input gadgets.

It legitimizes its high approximately $1,000 cost with a top-notch screen fit for a 144Hz invigorate rate and a discernibly more extensive field of view, just as controllers that tie to your hands and let you completely open your fingers, which it can follow separately.

It’s forward-looking right now, so early adopters probably won’t see its maximum capacity for some time, yet even now, the Index is seemingly the ideal approach to encounter VR.

Bottom Line

Valve Index is a premium PC VR, and the Cosmos is the king of inside-out tracking. The Index is undeniably the best PC-tethered VR headset you can buy right now, but it will cost you big.

Index’ external tracking (through the base stations), exceptionally brilliant motion controllers, and an outstanding display make it worth the money for each virtual reality enthusiast.

However, the Cosmos is a follow-up to the original Vive by HTC, this time with a supreme inside-out tracking improvement and a much higher resolution.

Its a solid performer but can’t match with what the Index offers, unfortunately, though it does cost less. The Vive offers a higher 144Hz refresh rate, maximum 130-degree field of view, adjustable eye relief, and IPD. The Vive is a comfortable fit with precise external tracking (through the base stations).

Furthermore, the Cosmos offers a full system at a low price, which is compatible with Vive wireless adapter and a comfortable build.

It has a slightly higher resolution as compared to the Index, and it’s designed modularly for wireless connection and accurate external tracking (through the base stations). Both VRs are advanced options that require a high-quality PC to run.

HTC’s Cosmos is the next version of the original Vive, bringing in a more comfortable halo headband with a lot of padding to increase the level of comfortability that is never experienced before.

On its back-side is a dial that is used to change its tightness, and its first presentation partition is pivoted so you can flip it up to see your global environment surroundings without expelling the whole VR.

There are some extraordinary face gaskets included, and even those with solution edges should find that the Cosmos fits comfortably. Valve’s Index has a similar ergonomic design, with a dial on its back-side for altering the tightness.

Furthermore, the point where these two VRs begin to differ is in the motion/environmental tracking and handheld motion controllers. The Valve Index relies on a minimum of two base stations for precisely accurate external tracking.

The most recent SteamVR 2.0 base stations included in the full Index system deliver an exceptional virtual reality experience. However, the original SteamVR 1.0 base stations that shipped with the original HTC VR also works fine. The base stations require a bit longer to set up, but they’re going to deliver far more reliable and realistic tracking.

The Cosmos depends on six built-in tracking cameras to follow the VR and its controllers in space. This is a similar tracking thought Oculus has for its Rift S tracking and Quest tracking frameworks.

Playing with Vive Cosmos

Valve Index vs. Cosmos: Introduction

Our experts deeply experienced both VRs tracking aside, because the majority of people know inside-out tracking will never compare to the Light House (Base Stations) tracking because the accuracy we can have by Light House tracking Base Stations can never be achieved through inside-out tracking.

Despite the Cosmos having the larger display resolution over the Index, the visual quality of the Index is much better. The color reproduction in the Index is also over the Cosmos.

The HTC Cosmos and Valve Index are irrefutably two of the best VR devices in the market at present. They offer the best resolutions and exceptional experience to make augmented reality as vivid as could be expected under the circumstances.

These two VR devices are entirely a long way from one another concerning cost. The Cosmos has a value of approximately $700, while the Valve Index has a high price of nearly $1000.

The Valve Index is one of the reliable and most costly VR devices in the market. The cost goes up to this as a result of the set that comes with the VR.

HTC Vive Cosmos & Valve Index are PC-tethered virtual reality devices. Furthermore, both VR devices require a high-end gaming PC to operate.

The Cosmos has an up on this as it is compatible with HTC’s wireless adapter. At the same time, the Valve Index, despite everything, utilizes wires to interface with a PC; in other words, the Index is an utterly PC-tethered VR.

If you are thinking about what is best for you, our experts can say that they are both. In this comparison, we will determine their similarities and differences for you to decide which VR fits you best and may earn your trust.

Valve Index vs. Cosmos: Tech Specs

Valve Index vs. Cosmos is as unique as they both are. When it comes to the tech specs, both VR devices are solid performers in their way.

The Index likewise utilizes double LCD and has barely any screen-door effect. The screen doesn’t flip over the head like the Cosmos, yet it, despite everything, has a passthrough highlight and is more similar to original Vive by HTC.

The two tracking cameras mounted at the base of the VR are utilized to interact with the physical environment. It can show your environmental factors without evacuating the VR or even the faceplate itself. The Cosmos has a somewhat higher resolution, yet it indeed doesn’t have an enormous effect.

The higher resolution of the Index is better than a portion of the VR devices out there, so it doesn’t have any issues with regards to the presentation and may earn your trust by its unique display.

USB 3.0 is the third biggest update of the Universal Serial Bus standard for interfacing computers and VR devices. However, both VR devices support USB 3.0, but the Index is also supported by USB 2.0. Furthermore, Cosmos’ initial requirement is USB 3.0, and Index performance remains the same with both USB versions.

The HTC Vive Cosmos controllers use mild for the trackers to discover it even in darkish rooms. Because of this, it makes use of more strength and requires AA batteries for each controller.

The Index controllers are arguably lovely in the sport right now. It includes touchpads and an analog joystick.

External tracking (through the base stations) vs. inside-out tracking is also an essential factor. However, it mostly depends on the comfortability of the user.

With the Index’ pressure and contact tracking system (including external base stations), you experience a herbal enter in the sport with every circulate of each finger.

The Index makes use of outside tracking (through the base stations) that’s more accurate than that of the Vive Cosmos’ tracking. It allows a room-scale VR enjoyable and exceptionally immersive.

Display Resolution

Vive Cosmos has a built-in flip screen feature that enables you to be more aware of what is around you. You can quickly flip the screen up to your head without taking the effort yo removing the entire VR.

Thie feature is perfect for multiplayer gamers or social activities as you can easily access the real world from the virtual reality environment. The Vive Cosmos flaunts 1440 by 1700 pixels per eye for the display resolution.

The Vive Cosmos is considered as the best & newest VR with high display resolution in the market. However, that isn’t sufficient; the Vive Cosmos utilizes a 3.4″ RGB LCD, which makes the presentation progressively immersive and vivid.

The screen likewise permits the pixel density to output better visual quality. The VR covers the entire top of your head—this dodges interruption from the outside environment.

The Index has a somewhat lower display resolution of 1440 by 1600 for each eye. Even though this is a slightly lower display resolution contrasted with the Vive VR, this display resolution is entirely reasonable for most of the VR devices in the market.

Refresh Rate

Refresh Rate is a general term which determines how rapidly the VR can refresh itself per second. The more the refresh rate, the smoother and higher the display visuals and VR experience will be. If your VR has a high RR, the transitions will be more seamless and faster.

This is a good feature to reduce motion sickness. The Vive Cosmos can deliver a refresh rate of 90Hz. It can revitalize its display 90 times per second; this is pretty standard reading for the majority of VR devices in the market.

The Index has a higher RR (refresh rate) of 120Hz and an experimental 144Hz on SteamVR. Our experts believe that the 120Hz is more than enough for a smooth transition; however, if someone feels the need, you may try the 144Hz RR (refresh rate) with SteamVR.

What’s impressive about 120Hz RR is that it can be achieved through older software. It means that you don’t have to update or buy a high-functioning gaming PC to attain the smooth transitions of the Index.

The 144Hz RR, however, requires a high-end gaming PC to attain this refresh rate. Furthermore, it’s still experimental, so this means that you even do not need it right now and may again face problems, so stick to the 120Hz for now.


The Cosmos includes a mechanical adjustment for IPD (interpupillary distance, the area between your pupils), similar to the original Vive by HTC. The pupil distance of lenses within the VR headset can be adjusted from 61-73mm.

IPD permits the user to alter the gap between the lenses to align their eye with the optical center best. The physical IPD varies on Index goes from 58mm to 70mm, which covers the overwhelming majority of users.


Most users ought to have the option to locate an agreeable fit and require an extraordinary amount of prescription frames.

Like the Cosmos, headphones hang down from both sides convey high-quality audio. On both VR devices, the headphones can be expelled if you have your preference as a solution.


The gift of accuracy in tracking is the most valuable in the virtual reality world. Both VR devices have unique tracking abilities. However, Cosmos inside-out tracking is as individual as Index’ with external sensors.

The tracking determines how accurate the monitoring or the ability of tracking of the VR is. We will also discuss their controllers’ capabilities to present you with a concept of ways they experience in your hands.

The Vive Cosmos has 6 DOF (degrees of freedom) that makes use of the brand new tracking technology. The Vive Cosmos does not want outside tracking due to the six set up tracking cameras on itself.

The motion controllers of the Vive Cosmos can be appropriately tracked utilizing those tracking cameras. The inside-out tracking of the VR has been advanced already, and it has widened the range of movement allowed by the VR.

There is a mild distinction among the accuracy of tracking among inside-out tracking and external trackers (base stations). The outside trackers like base stations still have a correct tracking device; however, the new and improved inside-out tracking & movement tracking of the Vive Cosmos makes it almost the same as outside trackers (through the base stations).


Valve’s Index “Knuckles” controllers are ostensibly the best equipment accessible at this point. These controllers have a unique design that allows them to be strapped to your hand so you can release your grip without them falling endlessly.

Joined with pressure and touch tracking for your hands, you will get a personal input for whatever you’re encountering in virtual reality.

The motion controllers can be held in any manner and won’t lose track because of the external base stations.

The Cosmos comes with some reasonably extravagant motion controllers — they’re shrouded in a lit design that allows for tracking — that is reminiscent of Oculus Touch.

There’s a standard-sized ring used for tracking at the top of these controllers, and they sort of having a general pistol-grip design. They’re agreeable to hold, yet they don’t offer the same degree of input as you’ll get with the Knuckles controllers.

They also don’t convey about the same precision because of the inside-out tracking, and on the off chance that you choose to do the switch to external base stations, they will be rendered useless.

Field of View

Field of View determines how wide a person can experience or see in the headset. It’s the VR display that allows us to have in all points or angles possible.

The HTC Vive Cosmos has a 100-degrees FoV. This reading is slightly higher to the 90-degrees Field of View of most virtual reality headsets in the present.

The Index has a wider 130-degree FoV. This amount of FoV removes the google-feel of the headset.

The Index is from the best in this category because it allows you to see or experience the virtual reality immersiveness in a broader display. Still, it does not have a hard time with transitions because of the high refresh rate.

Valve Index vs. Cosmos: Features

Both VR devices contain unique features, mostly in design and display. What these exceptional virtual reality devices are sitting on is below described in detail.


HTC Vive Cosmos’ model is an improved VR contrasted with the original Vive. It has a strap that folds over your head. The VR is made out of lightweight plastic with a fascinating color. Rather than the standard moderate dark color, HTC settled on a dark blue color.

The VR has six designated cameras situated impeccably around the headset. The head strap has a dial behind where you can conform to accommodate your head most graciously conceivable.

It additionally has a refreshed pair of controllers. The past original Vive was just perfect with the Vive remote and Index controllers, the HTC Vive Cosmos, then again, is currently best with the more normalized Oculus Touch Controllers.

However, don’t get confounded; it is still compatible with the older controllers. It had recently adjusted the Oculus Touch Control, which uses in the virtual reality world is increasing day by day.

The HTC Vive Cosmos is a PC-powered headset. This implies it, despite everything, needs a PC to work appropriately. Furthermore, a tethered connection to the PC is optional. The HTC Vive Cosmos is the best with HTC’s most recent wireless adopter.

This wireless adopter utilizes the new Intel WiGig Technology. This conveys sound and video with 60GHz and permits smooth changes from the PC to the VR with speed and exactness.

The Index comes in with the VR and the new controllers, and Base Station Version 2.0, as well as, the VR likewise has a halo lash and a top-of-the-head strap too. There are two dials in the Index headset.

One dial is for the distance of the screen display from your eyes, which can be found on the left half of the headset. The other dial on the rear of the head is for you to adjust the strap in your comfort.

It is a dark VR with a shiny plastic front. It has two mounted tracking cameras at the base of the faceplate, which is utilized as a passthrough include, and this unique feature may earn your trust.

The tracking cameras are additionally said to have the capability of being utilized in augmented reality. This implies you can use your environmental factors and blend it in with your virtual reality games.

The Index has another controller, and they probably have the most refreshing component in the market. In any case, We will discuss that later. The Index is additionally good with HTC’s equipment. This implies you can utilize your original Vive controllers on the Index or the opposite way around.

The principal explanation for this is because both of their controllers are made on both SteamVR stages. You can blend and match the equipment for the HTC Vive Cosmos and Valve Index.

The Index is a PC-powered VR and still needs a wire to interface it with a PC. The incredible thing about this is the Valve Index conveys new goals even with decade-old programming.


HTC made a fantastic work boosting the display in the Cosmos. It’s a gigantic step up from the original Vive, with about a 88% display resolution knock.

It has dual LCDs with a combined 2880×1700 display resolution and scarcely any screen-door effect. Like Valve’s Index, the Cosmos features IPD adjustment dial so that a full scope of users can locate an agreeable fit. However, the Index also eliminates the majority of the screen-door effect.

Shockingly, the Cosmos does not have eye relief like the Index or original Vive by HTC, so FOV is topped at around 110°. With the help of its adjustable eye relief, the Index can hit around a 130° FOV.

The Index has a similar combined display resolution at 2880×1600 and features dual LCDs with negligible SDE. It can hit an astounding 144Hz refresh rate in an exploratory mode (with ground-breaking PC equipment), where-as the Cosmos is topped at a 90Hz refresh rate.

Either way, you are going to have an exceptionally brilliant picture. However, the Index wins in the display class and may earn your trust, thanks to its FOV and refresh rate.

Viveport permits all its virtual reality VR to expertise games that aren’t with alternative headsets. Viveport is HTC’s software package stores, and it contains tons of games that can be content with the original Vive Cosmos

Connecting the HTC Vive Cosmos along with your Steam account also will enable you to play games from SteamVR. It was at first unobtainable with the Cosmos; however, Valve has developed the changes required and allowed most of the VR headsets within the market to access their games through SteamVR.

The Index, of course, is compatible with SteamVR. There are problems that alternative headsets have the difficulty of connecting with Steam.

This drawback happens to most headsets, particularly on the primary strive. However, Valve has developed solutions concerning this, and also the method has been higher over the years.

We say that virtual reality high-quality gaming on the Index is best because it includes a lot more precise motion and movement tracking (through the base stations) with its new 2.0 base stations external motion/movement tracking system. The original Vive Cosmos is more comfortable to move because it doesn’t have any wires.

There is a touch delay on the Cosmos controllers; however, it’s hardly noticeable, and you’ll be able to play your games with swish transitions still.


To experience these beats, a powerful & high-end gaming PC is a must. A great experience comes with a high price, and to have an immersive virtual reality experience and reliable performance, a powerful PC is required.
