Hi guys.. i played 2.5.5 a long time and have changed to 2.5.6 and have rly problems with VR.   
my Settings in 2.5.5 was SS to 180% and PD 1.0 ingame the most setting are low or off. I got 45 fps stable with my HP reverb.   
NOW! 2.5.6 i have to set SS to 160% and have rly bad performace like 30 fps. did they anything changed so hard?   
have anybody the same issues? Bad Performaces after 2.5.5?   
my GPU is a 1080TI and worked fine with 2.5.5.
