780 TI, i5 OC'ed to 4 GHZ
Everything set to low / disabled, even using a mod to disable tree shadows. Dropping below 75 (sometimes even below 50) in the 1.5 map when flying over / looking at villages or airports. DCS in its current state does not work properly in VR, at least on my machine. Only really works when you're flying at high altitudes (so less objects are rendered) or over empty terrain / open sea.
I used to be able to run DCS in VR on lowest settings a few months back, performance seems to have actually gotten worse since then. Or maybe something changed on my machine, but I don't seem to be the only one who has that impression
Regardless of actual graphics, it is simply impossible to play some campaign missions in VR. As soon as there are too many AI ground units your CPU becomes a massive bottleneck, even if there are no objects actually visible on the screen
Once 1.3 releases and the juddering gets (hopefully) fixed framedrops shouldn't at least make you nauseous anymore, but I think it'll still be noticeable and might ruin any subconscious feeling of presence
