Saw this guide that uses the VR mod here recently:
…and it mentions in the video description a multiplayer integrity check ok version that I might try. I am more or less ok DCS performance wise, but always curious to see whats up.
Things I picked up from the video:
-
DCS Terrain textures to LOW helps VRAM but doesn’t change much in visual fidelity. Curious to try this now.
-
Nvidia control panel stuff, to set VR Preframes to the max (4 I think) to reduce missed frames (rather than increase framerate). The argument against this pre-rendering is about latency of inputs (as the frames are queued up by the CPU). Again, might be worth a try.
Everything else seemed ok, although aiming for 60 fps is a nice luxury as the Index can go to 120hz. For Rift S the goal would be a solid 40 and for WMR a solid 45, both with their various reprojection magic on.
Just for reference, here’s some video screenshots (saves me typing 
) of the important bits the author recommends trying:
Some of these in DCS are a bit brutal, but whatever floats your boat/framerate I guess:
