The Resident Evil 3 demo dropped yesterday, and the game is unquestionably a visual stunner, but a framerate analysis by YouTube channel VG Tech reveals some inconsistencies in performance between platforms. Basically, while the PS4 Pro provides a near-perfect 60fps, the Xbox One X is surprisingly all over the map. See for yourself in the comparison video below.

According to VG Tech, the Resident Evil 3 demo runs at a full 4K on Xbox One X, 2880x1620 on PS4 Pro, 1080p on the base PS4, and has a variable resolution that can drop as low as 1728x972 on Xbox One S. Unfortunately, it seems the Xbox One X pays for its full 4K resolution, as its framerate bounces all over the place, occasionally dropping into the low 30fps range. Only the Xbox One S delivers worse performance, although not  by much, sometimes dipping below the 30fps mark. Meanwhile, the PS4 Pro delivers a near-perfect 60fps, only shaving off a frame or two during big explosions and the like, and the base PS4 mostly hovers around the 40fps range. So yeah, a pretty wide range of results for a modern multiplatform title.
