Valve Index vs HP Reverb (my thoughts after trying them both extensively)

Yes i have tried both the HP Reverb and the Valve Index.

2,5 weeks ago i received my HP Reverb and last Friday i got the Valve Index. One of them is boxed up and leaving today, the other one is still connected to my PC guess which one i'm keeping :)






I pre-ordered both HMD's because i wanted to eliminate all doubt whether i got the right one. I have been using the HP Reverb for more than 2 weeks and the Index for almost a week now and for me the Valve Index is the clear winner.

I liked the HP Reverb for the pixel density, but there were 4 major cons that really made the HMD definitely lose the battle from the Index

- Big bulky cable with gigantic connecter
- Comfort. There's a really sharp edge behind the nose flap. If your nose is bigger than average, the HMD will touch it there up to a point you can't even use the HMD anymore
- Build quality : loose connectors, earpod broke down after 1 week already
- Windows WMR: very buggy, lot's of restarts


HP Reverb

I really wanted the HP Reverb to work, so i

-3D printed a clamp for over the connector the battle the disconnects
-3D printed a special cable holder that was velcro-ed to the back of my GS-5
-Added a extra head strap to prevent the HMD from touching my nose
-Created the right routine by calibrating the HMD first, mounting the cable to my GS-5 before starting other programs

The picture quality dead center is amazing, but the sweet spot is very narrow. As soon as you look around in the HMD things get blurry pretty fast. When looking at a distance the HP Reverb was giving me crossed eyed vision, it was way too bright and the colours looked washed out. The brightness can be fixed in Iracing, but not in all sims.

So i started to develop a love hate relation with the HMD. Loving on some parts but really hating it on others. I even put it up for sale for a short while, but removed the add a day later.

Windows WMR
WMR is a PITA. You always have to put the HMD on and look left and right and down before you can start your sims, but if i launched simcommander and simfeedback before calibrating the HMD the tracking was jittery and only a restart would fix it. Sometimes WMR decided that my mouse only should work on the desktop and not in VR. There's a quick key to switch it back in to VR (win+y), but that key does not always work. Only a windows restart fixes this.

Comfort
The HMD itself is really light and comfortable, but the cable is so heavy that if you stand up and let it hang, it skews the HMD. The bulky connector hangs around your neck and is again not the best solution out there. With quite some effort i got this fixed. The biggest problem was however the sharp edge behind the nose flap.The HMD has a very narrow sweet spot to adjust it on your head, i had to adjust mine that this sharp edges is only a mm or so above my nose. During racing with motion it started to touch my nose very frequently, so much that the day after my nose would hurt when putting reading glasses on.

Image quality
Dead center, really awesome sharpness. Unmatched by any HMD, but as soon as you look of center thing get blurry really fast.

When you drive into a corner, the center of the HMD is looking at the APEX in the picture above because this is were you are naturally moving your head. This part is really clear and crisp. But in a race, you often find yourself doing a quick glance with your eyes at the car in front of you. This car is, like the one in the picture above, of center and it becomes much more blurry when looking at it with only your eyes and not moving your entire head.

Like mentioned above, dead center really sharp but when looking at the distance it gave me a crossed eye view. Not sure how to describe it was like there's a rgb pixel blur around the edges of objects in the distance. Mura is there if you look for it (looking at the sky), but hardly a factor when driving.

Tracking
Tracking in of the HP Reverb is fine as long as, you are not using heavy motion or you don't have a monitor beside your rig.
Unfortunately i have both. Large and fast left/right movements resulted a lot times in viewpoint shifts. The internal gyro can make the image inside shaky when using heavy motion

Not being able to place the monitor directly beside me gave me all sort of discomforts when launching steam / simcommander ect ect when i was already strapped into the GS-5. No being able to see the icons because the monitor was too far away.

Build quality
The headset is light and feels cheap, but if it works that's ok, right? In the end the cheap build quality is what saved me. The bad connectors and the already broken earpod gave me the opportunity to send it back to HP as a DOA and get my money back.




Last week even before the Valve Index arrived and before i considered the possibility to return my Reverb to HP, i decided i would not be keeping the HP Reverb. I had a pretty bad concern that the Valve Index with the lighthouses 2.0 could have a tracking issue cause by the EMI of the Servo.

I have 4 SFX100 servos, 1 seatbelt tensioner servo, 4x GS-5 servos and 1 AccuForce servo, plus 2 seaflow blowers.

So the concern that the Valve Index would have EMI tracking issues was pretty big. That's why i wanted the HP Reverb to work, having seen that clarity, i could never go back to the Rift CV1. I decided if the Valve Index would not work, i would give up on VR and buy a Samsung 49" widescreen.


On june 28th i got the pre-ordered Valve Index.

As soons as i opened up the box, i immediately sensed that this is a different product. The whole build quality of the HMD is in a different league. The comfort is unmatched. Everything feels so premium.

This was my initial impression before connecting the HMD to the PC. With high anticipation it was time to install and connect it to my PC

SteamVR automatically sets my resolution to 150% since i'm using a 2080Ti. Getting used to the HP Reverb quality i expected the worst, i loaded up a race sim a put the Index on my head.

I was blown away with the difference between the Valve Index and the HP Reverb. The colours were bright, but spot on, good contrast, good blacks, but mainly the overall clarity was mind blowing. The FOV was quite a lot bigger, most of the gain is horizontal though. I can't explain why but i'm getting a better depth perception.

The sum it in one word: presence

screen
The total pixel count of the Valve Index is lower than the HP Reverb. The HP Reverb is sharper dead center, but looking at the entire image inside the HMD from left to right the Valve Index wins for me. Just slightly looking with your eyes of center results in a much clearer experience. Displays on steering wheels can be read much better with just moving your eyes only.
The colours are vibrant, the contrast and black levels are spot on. You have multiple choices between the different Hz modes and running it at 120Hz is pretty cool, but..... only for hotlapping.

Running a full grid with a decent 150% supersampling and good ingame details will set you back to the smoothing of steamVR at 60fps.
There has been a lot talk about running in 120/144Hz but the current hardware is just not fast enough to run it permanently at those frames on demanding tracks with a lot of cars on screen. Most of the FOV gain is vertically, i still have to physically move my head to see the mirrors.


Build quality
Everything about the Valve Index feels premium and well constructed. The construction of the head strap adjustment, the speakers and the eye relief knob are all great quality. The cable is nice and long and not heavy at all. Very easy to swap between different face gaskets is just the icing on the cake.

Comfort
The comfort of the Index exceeds the comfort of the Reverb in such a way that it's in a entirely different category. The face gasket is nice and thick and feels really good. With the HMD on your head, you can easily turn the knob at the back to tighten or loosen the head strap. Even while racing on the straight. Depending on the intensity of motion i'm running, i can tighten or loosen the head strap without having to take the HMD of. I don't feel the cable pulling at all. There's plenty of room for my nose.It did take me a couple of day to recover from using the HP Reverb.

Audio
Class leading, period. I was afraid since the speakers don't isolate my ears, that the noise of the motion and the very noisy GS-5 still could heard when driving. I'm glad to say that this is not the case. It does a better job at masking the motion sounds than my rift CV1 did. Crewchief or any other digital race engineer can be heard a lot better, but he/she also hears you a lot better because of the high quality mice that is used.

Steam VR
In steam of WMR / SteamVR just works, the mouse in where you want it everytime, audio switches to the HMD. It's almost trouble free

Tracking (with motion)
You can run it with one lighthouse and you don't need the controllers to do the setup. 2 lighthouse does give better tracking when looking down or extremely left or right. The tracking with motion has been flawless. Obviously the lighthouses are placed of the rig.

There's an issue with loss of tracking when i touch the HMD with my hands at the front when the motion servos are powered. This will result in a grey screen, which immediately come back. However if i hold it too long it the tracking because lost and a restart of steam VR is necessary. I found a way around this by either temporary disabling the motion or move the HDM at the very front of the head strap.

HMD not starting
However there's one rather big issue with the Valve Index. As soons as the Index is connected to my PC, it takes about 4-5 min longer to booth. After boothing often the Index is not recognized anymore and needs to be re-plugged. I suspect this is happening because the PC is trying to booth from the Index and somehow sets it in an error state.

This issue is "currently under investigation" by Valve.

I initially had cancelled my Virtual Link adapter for the Index, but have re-ordered it since i believe it will solve this issue when the HMD is plugged into the back of the 2080Ti.

summary
Overall, i'm glad i got to try both HMD's. Otherwise i would have always been wondering if i should have gotten the other one. The best VR headset of the 2 is the Valve Index for me. Of course the ultimate VR headset would have been the Valve Index with the resolution of the HP Reverb. Because of the pixel count i always suspected that the HP Reverb would have been the clear winner, but in the end after having tried them both it's i can say it's not even a close battle
 
Another question... I have a Nvidia GTX 780 which is around as powerful as the minimum recommended GTX 970.

The 780 GTX has a display port output, version 1.2 I believe. But are there any requirements as to what version that display port should be of? Or will the index work with any version of display port?

And what about the usb 3 connector? I have only usb 2 (I believe) on my PC. Normally it's for the cameras on the index which I don't need. But will the index connect/work without the usb 3 beeing connected? Or it being connected to a usb 2

Henk, how about god-rays? It's the one thing I've seen mentioned negatively in regards to the Index...are they there? Are they bad? How do they compare to Rift god-rays (which are awful)?

God-ray are much less than the CV1, but on the CV1 it never bother me either. So i'm probably not THE best person to ask. :D

On a regular image (not just a blackscreen with white letters) the god rays are more commonly called "smudge" because they are so prevalent and appear like a layer of vaseline killing the already poor resolution and details of the screens. They are always present on that headset. I dont miss the CV1 at all.

If some of you wear glasses, smudge your fingers on the lenses and turn your head in circles against a light source. Thats how the CV1 looks with bright scenes

Bright driver suit in cockpit view can make everything look hazy like Dan explained.

This is a through the lenses shot of the index
There are no real "god rays", but the brighter light is reflected inside the lenses and you can see the frenel circles on the outside and more reflections in the lenses.

(ignore the vertical stribes, it's my cell phone)

Looking forward to retiring my CV1. It's gotten some good use by at least 25 different people all of whom experienced VR for the first time except a few who had tried an Oculus Go.

The Index is the first system that feels worthy of replacing my trusty Rift. Until the Index everything else has had a dealbreaker of some kind.

Thanks for this great review.
Great to hear that you don’t have tracking issues with motion.
This Valve will be my next VR headset but first I need to upgrade my GPU.

Ive not tried ACC in VR yet and know it isn't the best configured

Suggestion:
Although it may be an excellent title to set a night race and test out the GLARE from cockpit dash and cars taillights etc.

There will be always a review that is pro one or against the over.
Early model, I don’t know. There are not many people who got the 8k and I am one of the last batch from the Kickstarter campaign.

If you compare pimax to index it’s comparing a budget car versus a Mercedes.
It is the whole package that makes the index so much better.

Do not get me wrong I do like my 8k.
It does some things really good.
Pimax is good for videos (minor light bleeding on high contrast scenes), some titles like ACC are better because of the fixed foveated rendering and of course the wide fov.

Then on the other hand pimax is doing its own way by hooking many of the DLL and not implementing the official API.
That means if the official official gets an update they need to patch it again.
The tracking is not reliable I have to find out a specific start-up sequence to get my headset tracked every time.
All in all it’s too much hassle .

But if I had to choose one it will always be the index.
It is much more comfortable and does not give me any eyestrain, has wonderful colours and everything is crisp and clear .

Hey, That’s just me

I think it's pretty obvious that the Index is the best thing going and will likely remain so for a while.

However a lot of people are upset that it's not OLED or that it's not inside out tracking or don't like the price. For these people there will be much gnashing of teeth for the foreseeable future.

Right now all solutions are a compromise between opposing priorities.
  • Resolution vs fps ( Current hardware simply can't drive both )
    • Lump in FOV which has extra resolution in here as well.
  • color rendering vs. refresh rate
  • tracking accuracy vs. convenience
  • quality vs price
Based on the pace of current computer hardware it appears that we won't have a cake and eat it solution for quite a few years, so prepare for a lot of people being upset.

There are still Vive Cosmos and Samsung, so that "for a while" could be relatively short.

There are still Vive Cosmos and Samsung, so that "for a while" could be relatively short.

Could be...

Has Samsung actually hinted at a product yet? I found one article saying that they planned AR/VR releases over the coming months, but there is no hint as to what they will be yet. Since AR is a different market, and VR includes stand alone devices like the Oculus Go and Quest, the question is what direction(s) they have decided to pursue. They have specifically said that they are looking to improve on their GearVR product line and Galaxy based VR. So until they make announcements, we have no idea if there will even be a new PC product.

HTC needs a win, but that is partly because of their track record. Think about where the Cosmos is aiming. It will require a premium PC, but it's down market from the Index and won't be the solution most room scale enthusiasts go for. Given their Vive Pro System was priced hundreds more than the Index, the odds of their new product being good bang for the buck is questionable.

For the record I love many Samsung products. I have a Samsung Galaxy phone, UHD TV, Washer and Dryer, even a refrigerator and I like their SSD's among other products they make. They are very competitive in many markets and quite possibly the largest player in this whole arena. I have no doubt they could flex their muscles and I hope they do! I just have trouble predicting a product launch based on a patent.

For some reason the article below picked out the Oculus Quest as being the most likely to get competition from Samsung. Probably a dart's throw, but it is a much larger potential market.
