Hey there,
I have a Vive pro with a 1080Ti - I couldnt find much Vive info out there and just fiddled with different settings like did and what i found is to disable ‘Motion Smoothing’ in SteamVR. This made a huge difference. I also found that contrary to what so many people advise, setting the Render Scale to 100 made the sim look great and also gave a framerate boost.
I get a much better graphical result in MSFS than I do in DCS since I changed the Motion Smoothing setting.
good luck mate
