These were the values I ended up with on DCS before my crash woes. I did have to up the in-game gamma a bit (the value in DCS options) to about 2.6 ish, but it’s really taste dependent. Mine looks a bit cartoonish, plus if you hate jaggies and must run lots of MSAA in VR then you might hate these values, but put here anyway:
ReShadePreset.ini complete:
PreprocessorDefinitions=
Techniques=VRSharpenColor@VR_CAS_Color.fx
TechniqueSorting=VRSharpenColor@VR_CAS_Color.fx
[VR_CAS_Color.fx]
Brightness=0.985000
CASContrast=0.600000
Contrast=1.001000
MaxDelta=0.100000
Saturation=1.100000
Sharpening=1.900000
SharpeningRadius=1.000000
SingleImage=1
Note: these are for the CASShaderV2 from above, as it includes a SharpeningRadius.
Also, once you are happy with any values (you can adjust them on the VR 2D mirror) then on the bottom right of the main Settings page you can hit ‘Performance Mode - 
’ and that’ll give a small performance boost (it effectively freezes the shaders from taking new values, so they don’t need to recompile on each change etc).
