Running v63, force_oculus works for me, but it does not matter. Any API that I run does not matter after latest DCS patch, be it oculus, openxr or steam, I get the same problem - MT is pointless for me in VR, it utilizes 1 core and the res 11 can go **** of. Funny thing is, as soon as I switch to flat screen, everything is running better tan fine.
And this started after the last DCS update for me.
Also fun fact while running MT on 1 core, winding up the setting so that DCS is CPU limited and drops to 30 fps, as soon as I alt-tab out of the reprojection window (out of focus), fps jumps up to 70-90. . . .
