SteamVR Frametime Spiking

[Astronomacle]

Hi, I recently received my Valve Index and everything's been great, besides some frametime drops which are really annoying. I've been troubleshooting for the past few days and can't seem to find a solution. I think the cause is from the CPU which apparently is because "the CPU isn't sending the call to draw the next frame to the GPU".

So far I've tried...

 

• Turning off hardware accelerated GPU scheduling
• Turning off ReBar
• Turning off XMP
• Closing Hardware monitoring softwares
• Changing power plan
• Verifying games and SteamVR

 

My hardware has not been overclocked besides XMP.

My hardware :

GPU : RTX 4090

CPU : i9-12900K

RAM : DDR4 3600mhz

OS : Windows 11 Home

 

Any help would be greatly appreciated!
