Anyone find a solution to this issue? I have been fighting this framerate issue with the wireless adapter on iRacing since about October as well. Before October I had no issues with holding 90FPS. Works great with the cable(Link box) solid 90FPS but the instant I reinstall the wireless adapter it drops to 50-60 FPS or lower. Also other games like Skyrim and Fall Out 4 have pixelation and frame loss issues. I've completely reset my PC, wiped all drives and clean installed Windows and all HTC Software. I'm literally about to by a Quest 2, I have been happy with my HTC Vive up until this point.
My hardware is as follows:
I7 9700K OC to 5.0GHZ
2700MHZ 32GB Ram
RTX2080Ti
