My 6800XT does great with my HP Reverb. The frame pacing feels better than my 3080Ti.
AMD's reprojection implimentation doesn't seem to work as well as Nvidia's though, so when the GPU starts to struggle, the 3080Ti is playable and the 6800XT is not so much. (Just have to leave a little more headroom with setting selection on the 6800XT)
There's alao an issue with the latest drivers showing performance regression in Project Cars 2 for me.
Oh, and Nvidia seems very picky about what monitoring software I have running. Afterburner causes stuttering and frame drops. Same with WHinfo. FPS VR seems to be fine after one of the recent updates.
6800XT seems oblivious to monitoring software, which is good.
The PC2 driver regression is the only thing that makes me want to hold off on AMD's new stuff, but Nvidia has their own issues with cable roulette, so I could still go with either brand for an upgrade.
