That video of Shadow of the tombraider 12:02 on that 6900XT is hitching like hell. AMD still not fixed frame pacing then? IT was the bain of my life in some games on my 7970Ghz
15:30 LOLOLOLOLOLOL!
AMD fixed it years ago. In this case it's most likely either the engine or the video recording, both the 3090 and 6900XT can slowdown in SOTR and actually, across a selection of games its the 3090 that looks a bit rough on the graph although, it has to be said, it is probably undetectable to the eye as both cards deliver great performance.
