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

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.
Another Gear VR perhaps.

Thanks great review, HoiHman.
You say that the sweet spot of the HP Reverb is narrow.
How long(or much) is your IPD? I want to know if it is an average value.

Distribution-of-IPD-for-the-entire-ANSUR-database-The-bars-show-the-number-of-subjects.png


As you know, the IPD of the HP Reverb can be adjusted from 55 to 71 mm with software.
But the softwear adjustment is unfortunately not perfect. It can often not fit people who do not have an average value IPD.

On the other hand, the Valve Index can be adjusted from 58 to 70 mm with hardwear.
The hardware adjustment can fit all IPDs.

I think that it is useful for many people to know the review written by person how long(or much) IPD.

By the way, my IPD is 62.5 mm. I hope to be able to be fit with software adjustment.

Thx! No way, your IPD is normal in a bad way.
It may be that the sweet spot is just really narrow.
I am worried about my pre-order.

If you have a bigger than average nose and you play sims that have no brightness control, you should be worried.

Also be prepared to find a solution that will prevent the heavy cable pulling the HMD from your head, it's mandatory.

As you can see here, i really wanted the HP Reverb to work and put in quite some time to get an acceptable solution for the really really heavy cable.

I have been told by the HP reseller that they are exchanging all cables before they start selling the HMD again. 1 month is not enough to completely revise a VR headset and if they do revise it in such a short timeframe, i would stay far away from it.

For me the most important questions are not the technical ones. The VR industry is very young so the hardware and computing power is only going to be stronger. I am not worrying about that.

I am concerned with the ergonomics. In particular, how hot does the valve index get without a wind simulator? I know you use wind simulator. Unfortunately, my eyes get dry very quickly under strong wind so I really don't want to use that, but I don't want my headset gets dirty and uncomfortable because of sweating.

Another thing is about the weight distribution. How does the weight feel? Even if you mentioned that headset is light, one might feel dizzy if the center of gravity is placed at very front.

These two are some obvious flaws of the first gen HTC vive. I think I might be the first batch of users of VIVE and it just blew my mind, but I never used it for extended period of time because of the two issues I just described. I believe head movement has high frequency in simracing as you need to look to the apex. Some flaws can be enlarged over extended period of use.

Ergonomics of the Index are pretty good, but it's still something you have to place on your head/face.

Weight distribution is very good, but if i use really heavy motion i do have to tighten the HMD a bit more than i would like to, in order to keep it secure. That's more caused by the heavy motion and not the HMD it self.

Comfort wise my modded rift that hanged in front of my face was king. But the rift has been sold and i'm pretty happy with the Index.

I can't drive with a hot piece of hardware on my face without having the cooling of simwind. With the HMD on your head, you won't feel any wind in your eyes.

That seems to be an issue for some people and not others. The UploadVR people say they haven't found this to be an issue for them.

I imagine if you don't have AC it could be more of an issue.

Too bad because it's almost the only VR title I play. :(



:D

I've got a Valve Index on order, I've never tried VR so really keen to see how it feels in sim racing.

Currently I have an Ultrawide screen, I was tempted by 3 screens but the bulk and ugliness puts me off a little. Hopefully VR trumps both setups.

I don't think you'll be disappointed as long as your computer is pretty strong. VR has an impact that has to be experienced to understand well.

For you guys with SFX-100 and full chassis movers and the Index.

Are any of you using a Vive Tracker and the open source software to adjust motion relative to the tracker, or have you all just mounted your base stations to the moving chassis?

Question about the Index FOV, how close to your face does it have to be to get the max 130? I have one coming this week and I currently have a Rift which I play pulled away from my face from the bottom so there is enough room for me to stick a finger up and itch my nose if needed. This gives me the best clarity and comfort for long sessions. Will I be sacrificing FOV on the index doing this?

Neither. I've now settled on one lighthouse mounted externally directly in front and one front right corner and the tracking is perfect. Mounting the lighthouses on a motion rig is a 'no no' as the slightest movement will break tracking.

I did try motion comp using the input emulator plug-in and a Vive tracker (Puck 2.0) fixed to both the top of my seat and also to the rig, (secure and well-damped in both cases) but any small vibrations that the puck picked up ruined the experience. I might revisit when I have more time but in all honesty I'm completely happy as things stand so probably won't bother.
