    Nvidia has changed the render pipeline. Framedrops on Vive Pro 2+ RTX 4090.

    Good morning,

    I upgraded my RTX 3090 to a 4090 and I had significant lag and latency with my Vive Pro. I am a computer dealer and I tested several RTX 40xx cards with the same result.

    I identified ICue software from Corsair, Asus Aura and CoolerMaster Master+ as being responsible for the lags. For latency I followed this:


    I was able to remove latency by increasing the sync_photon by 7ms by pressing 7 times in SteamVR's Debug Command. This value can change according to your config.

    However, it must be done each time you start steamv.

    For jitters or stutters, close your monitor or RGB/ARGB services one by one via services.msc to see which ones are causing them and delete them.

    I hope that will help. Good game.

    Hey just wanted to provide an update since i have been experimenting with this alot:

     

    I was able to get this issue to happen with my vive pro >>>>1<<<< and 4090 now.

    Prior to this, i had always used the pro 2 wired and the pro 1 wireless... but when switching to pro 1 wired, the same stutters every 5 second and laggy tracking starts happening.

    The first time i loaded in with the pro 1, motion smoothing was on as well,  and this made everything 10x worse..

    After turning it off and then restarting steamvr, its back to the standard 5 second stutter and laggy tracking. 

     

    But its rather interesting... the pro 1 doesn't have the same DSC limitations as the pro 2, so must be something else with the vive driver causing the issue for 4090? 

    Also interesting that wireless doesnt have the issue.. I would wager that wireless also doesnt have the issue for pro 2 as well.. will need to try this next.

    Following up with my experience... Getting reprojection with Vive Pro 2 + 4090 in Beat Saber (One of the less demanding VR games), I am not even talking about the 120hz modes, getting reprojection in Ultra 90hz...with SteamVR and Vive console default settings
    What the f is going on? Is the Vive technical team working on a patch for this and when it will be release?? This is totally unacceptable
    Anybody knows if Valve Index has the same problems?
     

    Index only at 144hz. 120hz works fine. Its dp1.2

    @C.T.

    I had HW-accelerated gpu scheduling on initially, turned it off and no difference. 

    Also driver version makes no difference to the issue. 

     

    Testing in steamvr home:

    Try turning your head back and forth quickly and watch the screen latency with a 4090, swap to a 30 series and repeat the test.

    Should see the screen "catching up" by like 300ms with the 4090 vs being 100% in sync with 30 series. Also random 200ms screen freezes during this process.
