The problem I have is that godrays and that noticeable (for me) jump in clarity are my thing
That new Driver 430.86 is not the fix. All you may try is running the 3 Oculus exe in Tasks as High OR Realtime (latter may cause other affects). We once needed to run OVRService as just 1 Core or more or something similar.
I always feel confident issues will be fixed just after having a decent coffee.
The same thing happens with my views of the world in general.
