Headset tracking delay problem with RTX 4070Ti

[RaMen]

I upgraded GPU RTX 3070 with RTX 4070Ti and there was a problem in all VR app including SteamVR Home. When you shake your head, the objects you look at also shake a little. This is very uncomfortable. It's like there's a tracking delay between the movement of the headset and the image. I never had such an effect with the RTX 3070 card and even with GTX 1070. When I installed 3070 back, everything become fine in VR without any other changes in PC or any apps. Then I installed 4070Ti again and the problem reappeared. It makes VR almost unusable...

It's definitely not a perfomance problem, frames time is 6-8 ms in SteamVR Home on both GPU's without stuttering. CPU and GPU usage in normal. I have latest NVIDIA GPU drivers 528.24 and latest SteamVR, also I tried use SteamVR 1.25.3 beta. Turning on/off "Windows GPU Hardware Scheduling" doesn't take effect. Reinstalling headset drivers and SteamVR also doesn't solve promlem.

System specs: HTC Vive Pro, Windows 10 22H2, Ryzen7 5800X, 32GB RAM, Palit GeForce RTX 4070 Ti GameRock Classic.

Does anyone have the same problem or any ideas? Heeelp... T_T

Suspect USB congestion. Start eliminating USB hogs:
1) webcams
2) RGB anything: GPU, KB, Mouse, case. Disable or uninstall RGB software.
3) "Gaming" anything: KB with custom software, mouse with custom software. Test with a basic kb and a basic mouse using default windows drivers.
4) Peripherals: unused joysticks, HOTAS, gamepads. Unplug them all for testing.
5) "Optimization" or "AI" software from your OEM or motherboard maker.

If you find a culprit you might be able to still use it by moving it to a different USB host on the motherboard.

What happens if you disable direct display? ( https://steamcommunity.com/app/1635730/discussions/0/3764481749070910000/?tscn=1675655707 )

Thanks for your answers. Any manipulations with USB do not work. I tried to disconnect all devices except the mouse, connected Vive to different ports (2.0/3.0). Also with RTX 3070 Vive works fine with connected to USB ports KB, mouse, gamepad and three external USB HDD at the same time.

But when I disabled direct display and turned off/on the Vive, the delays disappeared! Then I tried turning direct display on and off several times. There are tracking delays in direct display mode, and when it is off, everything works fine.

It looks like NVIDIA drivers problem... Or SteamVR.

Ok so I'm also the guy that figured out the direct display fix, I'll forward that info to HTC b/c we have that in common and that must be related to our problems!
