Initial testing of the steam version and there's a few things I can say about it right off the bat:
Game is properly multithreaded (across 4c, haven't checked threads yet), which is kind of shocking for a capcom game. Ryzen folks should be happy with this one. Also seems really CPU limited with GPU usage rarely hovering in the upper 90s even at 4K.
Resolution hammers performance. I lost 30-35 FPS on the jump between 1080p and 1440p. PS4 players, I wouldn't really be holding out much hope for serious supersampling in this game on the pro version.
Game runs well on my end. ~60fps @ 1440p, ~90 @ 1080p, ~25fps @4k, all at beginning of game when linear so perf most def takes a dump later when shit gets real...but I've got the game installed on an M2 drive, running on 3200MHz RAM, a very stoutly overclocked 980ti, and a 7700k @ 4.8ghz, so who knows if you will have luck on more modest builds.
To the guy with the stuttering issues: the game doesn't even seem to use a full 4 GB VRAM even on ultra @ 4k, so I doubt it's vram related. What's your cpu? Game might be smashing it.
