Screen flickering in Steam menus

Hi, I updated my pitool to see if I could get better perf in halflife alyx. Unfortunately this causes my headset to start flickering in all the menus. Anyone know how to fix this ?

I’ve got the same issue. Mostly affects the SteamVR menus. On 90Hz it’s annoying 72Hz it’s barely possible to navigate the SteamVR menu. I’ve had the current Pitool since release and only noticed the flicker after the latest Nvidia driver update.

I figured it out. I think Steam gives the incorrect resolution in the settings now. Had it 100% and had to drop it to the recommended amount which was 44%. Restarted my PC and it was fixed.
