Valve/HTC Vive Discussion

The latest Vive Console beta is now on Steam.  It seems to have fixed jelly-like artifacts with motion smoothing (or compensation) which makes this a game changer for me.  I didn't have time to test it with other titles but DCS plays like a dream on my VP2 now with motion compensation on.  Without motion compensation the ground objects close to you become blurry during a gun run when you're close to the ground.

Good to hear I will have to check it out with my Vive Pro 2. I have had Motion Compensation turned off because it was so horrible.

Yeah I did a short free flight on the infamous Marinas map earlier and it was quite tolerable at 1:3 reprojection (30 fps on the main island) with no significant visual artifacts at all, not to mention 1:2 reprojection in other maps were buttery smooth.  So, it seems they also improved the frame pacing somehow.  The VP2 was really hampered by the software that wasn't quite ready for release, but this update seems to help unleash the true potential of this headset.  I didn't have time to do extensive testing but Vive's motion compensation did feel as good as SteamVR's motion smoothing.

Edit:  Forgot to mention that you can exit SteamVR without seeing the "SteamVR has crashed" window now.  You would still see that message if you close the Vive Console first though.  So the correct procedure is to exit SteamVR first then either leave the Vive console on or close it.

I need to get back to my DCS flying have not even tried it in Windows 11 yet, and anxious to try out Motion Compensation now in my Vive Pro 2 since it just got updated. Kind of got sidetracked with another game here last several days. Hoping to check this out here real soon.

Hi,
I have a question about the vive pro 2.
There is a ‘performance’ setting at half resolution and a refresh rate of 120Hz, intended for old hardware (such as my GTX1060, the minimum official requirement - of course, that's probably more to play beat sabers than DCS or Alyx).
In the Oculus Rift CV1, which natively runs at 90Hz, I can cap the refresh rate at 30 Hz (or 45Hz) with the oculus tray tool, to stay below the GPU bottleneck.  Then each frame is displayed 3 times (or twice at 45Hz). No interpolation (no motion compensation).  That works well for me.  I find it smoother than when I let the computer try to produce as many frames as possible (never getting above 45 fps anyway).
Is it possible to do the same with the vive pro 2 (lock the framerate at 30 or 40 Hz, with no frame interpolation/motion compensation, i.e. displaying the same frame 4 or 3 times when at 120Hz)? Maybe using the max framerate option in the Nvidia control panel? Or is that what the vp2 does automatically if motion compensation is turned off?

Thank you in advance.

Unless you have a very strong GPU I don't recommend 120Hz mode.  Reprojection and/or motion compensation work best at 1:2 ratio, so you'll want to aim for fps 45 for 90Hz or 60 for 120Hz for smooth gameplay and minimal artifacts.  1:3 is fine in slower games such as MSFS but not that great in DCS or fast action games.  As far as I know reprojection is always on for the VP2 so it'll fill in the missing frames to get to either 90 or 120 fps depending on the Hz, however motion compensation can be manually set to on or off.  The problem with using no motion compensation is that close objects such as buildings or ground targets become quite blurry when you fly over them (looking to the side and down), so I always have this on at the cost of a few ms of GPU frametime.

 

I'm not sure you can really cap any headset's refresh rate.  SteamVR has fixed throttling (capping fps, not refresh rate), but I don't think that applies to the VP2--haven't really tested it for this though.

Thank you.  Yeah what I meant was indeed 120 Hz with capping at 30 FPS (or 40) with no motion compensation. I got the terminology mixed up a bit, but you figured out what I meant.  Too bad that’s not possible with the VP2.  And yes I need a better GPU.  But they’re currently more expensive than the VP2 itself.. :-(.

hey guys! i upgraded from my vive to vive pro 2. i love it, but have an issue on some clarity. and i heard its a common thing with this. But i have a beefy system that has no issue running this. But everything isnt quite right. maybe its the eye dimensions? it just seems kinda hazy. like if u had finger smudges over the texts. everything looks great until i actually need to read it haha

 

EYE_LEFT = {
    L_OUT    =1.632019,
    L_IN    =0.834179,
    L_TOP    =1.111132,
    L_BTM    =1.132368,
}
EYE_RGHT = {
    R_OUT    =1.632019,
    R_IN    =0.834179,
    R_TOP    =1.111132,
    R_BTM    =1.132368,
}
 

 

But any help would be great! thanks i also have discord if thatll help with communication

Base station 2.0 are now in stock on Steam store, had been out of stock forever.  Now is a good time to buy, $50 cheaper than Vive store.  Note that version 2 is not compatible with version 1 and can’t be used together.

what would be the benefit of 2 over 1?

well i cant get my vive pro 2 to not be laggy and such. the performance for me is terrible. like horrible

[Johnny Dioxin]

People say a lot of nasty things about Valve support, but I've never had any issue with them, they've always been good to me (and efficient).

That hasn't changed - I just contacted them about my left controller having suffered a power surge while charging and even though they are 18 months past the warranty expiry date, Valve are replacing both controllers for me! They are also very keen to investigate exactly what caused the surge, I understand it has become a - not exactly common - but regularly reported issue.

Hats off to them - made me a happy camper!

I have seen nothing but praises for Valve support across the forums.

Ah well that is two different companies , my exerience with Vive Pro 2 was ok'ish but not great. 

Index rocked, just dated in the resolution and sde department now.

If you are using the current DCS Beta build and using OpenXR then you can use the OpenXR Toolkit to sharpen the image.

I've been using it with my Index for a couple weeks now, works great fie me.

Thanks. I have a problem with MT and Valve Index, it produces a los of stutters with motion smoothing ON. Seems very few people here with a Index, ... do you have fluid performance with MT and motion smoothin ON (40 or 45 fps limited)? Using OpenXR it could improve performance?

Its quite curious beacuse I have smooth fluid in MT 2D, 120 fps on Gsync (4090 and 5900x). But in VR... single thread is fluid but MT-VR is a stuttering fest.

Right now I'm getting a solid 60fps with DCS settings maxed out except for chimney smoke and MSAA at x2. No issues with MT, but I've turned Motion Smoothing on and off so many times while testing I don't remember where I left it. I'm also running the Index at 200% in SteamVR.

If you haven't already try clearing out the texture cache for DCS
