I know this is probably more SteamVR / Alyx, but I figured I would post here to see if anyone has any recommendations.
I'm experiencing extreme stuttering playing Half-Life: Alyx on my Vive Pro and original Vive. I cannot reproduce it in any other game. Sometimes I can play for a solid hour or two without any issues, then out of nowhere I get extreme, nonstop stuttering. Other times I start experiencing it immediately after loading a save. I can sometimes cause it to happen by using the weapon switching HUD. As soon as I open the weapon switching screen, it's non-stop stuttering. Opening the steam overlay / settings menu ALWAYS causes this if I am running Alyx. The steam overlay / settings menu never causes this issue if it's another game running. Sometimes if I exit out of Alyx to VR Home, the problem will extend to VR Home and be choppy there as well. I can't reproduce it in VR Home if I haven't first played Alyx. If anyone has additional recommendations other than reinstalling Windows, I'd love to hear it. Thanks.
GeForce GTX 980
MSI B450 TOMAHAWK MAX w/ latest firmware
AMD Ryzen 5 3600X
32 GB RAM
Windows 10 up-to-date
Vive Pro (and original Vive)
Original Vive controllers
1.0 basestations
The only thing that even remotely helps the issue is toggling async_mode_toggle (shift+a). When this is toggled off, the issue is almost completely eliminated, but if I lose a frame it jerks the screen pretty bad, and this happens freqently enough to make me not want to play like this. Seems like I really need this feature to be on.
Here's some things I've tried that did not help:
Plugged in my original Vive using the HDMI port, and experienced the same issues. Doesn't appear to be specific to the Vive Pro HMD.
Reseated every cable multiple times
Tried different USB ports
Tried a different port on my video card
Tried current Nvidia drivers, 445.75, as well as a few older ones (419.17, 397.93)
Completely removed Nvidia drivers with a 3rd party video card driver cleaner and clean installed
Updated all drivers using Snappy Driver Installer
Removed all SteamVR config files and completely uninstalled and reinstalled SteamVR
Set PC to 'High performance'
Set NVIDIA power management to Prefer maximum performance
Set SteamVR to disable power management
MSI motherboard but I've never installed afterburner
No hardware monitoring software installed
No overclocking software installed
System is not overclocked in any way
Removed Avast antivirus as it was on the conflicting software list
Disabled Windows Defender
No other software installed that is listed on the conflicting software for SteamVR
SteamVR motion smoothing on and off
Graphics and texture sizes set to lowest option
Tried SteamVR beta
Here's a few examples of what this looks like from the frame timing window:
Very bad stuttering after sometimes hours of playing without issue
in VIVE & VIVE Pro
