My 2070 super has been running everything smoothly on High at 3440x1440 (CPU is a Ryzen 5600X, game installed on an M.2 SSD). I haven't been closely monitoring frames, but I cannot think of a single instance where it's noticeably dropped, which for me usually means 50+ fps for games like this. I may even test running on some higher settings, but I've done very little tweaking/testing.

I did, however, install a mod from the very beginning that lets me use DSLL, which likely helps a ton.
