by the time CAPCOM fixed their stuttery, horrible DRM implementation on PC, PS5 users already finished the game and moved on to an another game while most PC users would still tinker with settings longer than they would originally play the game to get optimal frames/settings/tweaks. the game still is mostly a stutter fest due to DENUVO DRM, its just that people hate to admit some facts. e
and RT mod mostly runs at a locked, consistent 60 fps on PS5/xsx. even series s gets a nice 1440p rt mode with 35-45 fps. imagine you would need a rtx 2060 to match it (which by itself as of now is sold for 450+ dollar in scalp market)
once devs feel more comfortable with these machines and code only nextgen games tailored for specific nextgen console hardware and features, things will even improve further. this is just a stratch.
