For comparison. I just tried VR for the first time in DCS. I haven't done any configuring. I'm running a AMD 3700x, with 16 gigs 3600 DDR4 RAM, and a 2080 ti. In the F15C instant action Bomber interception mission, I got a solid 90 fps at altitude as soon as I get low it's 45 fps. Honestly couldn't tell the difference in visual and smoothness though.
