DF bench of the new DMC game.
PS5 gives Series X a pretty close run in all quality and RT modes, closer than would be expected.
In 120Hz mode, PS5 actually delivers a better experience. Overall, average frame rate in this mode works out the same on both consoles (100fps), but PS5 is more consistent, and maintains its frame rate during gameplay. Series X tends to lock 120fps in cut scenes, with frame rate varying wildly during combat.
DF state in the video that this isn't what they were expecting. They thought Series X would have a substantial advantage in all tests. And they propose that it could be API issues. IIRC, Microsoft made major updates to their dev tools over the summer.
It's 1 game, quite an assumption to make i think.
