Same here, after this thread / video (thanks by the way, I guess many people like me were waiting for this !) I started a little tweaking again (including even cleaning my GPU cooler :lol:) yesterday since I basically have the same setup as OP had (Zotac 1080 Ti, same CPU, RAM, ...).
I also tried Process Lasso again (did that several times but it never worked out) and my performance was about 5-15fps less. So I removed it like I did so often before and DCS actually runs better somehow. My CPU times are usually about ~15ms, so I wonder why his are so bad.
Went on PGAW yesterday with about 30 people on and had a fpsVR average of 42fps at 150% SS SteamVR on my Index (with Shadow mod).
Initially I was willing to spent the "big" money on the 3090 but after seeing these (first) results of the 3080 this seems like an even bigger waste (especially for DCS!) than I thought. Might end up waiting on the 20GB version of the RTX 3080
