It runs at locked 30fps, 1080p. Even if it just had a PS5 update it would be fine, but it's a bit tough on the eyes on a larger TV. Even a simple 60fps update would be enough, and a modder showed that even a PS4 can consistently hit 60fps playing it.
I was fine with 30fps for the longest time. I got a PS5 just last year and man, it really is rough going back to 30fps after playing everything else in 60.
