Quality mode seems like it might want to target 30fps, but instead it tends to fluctuate between 31 and 36fps - truly bizarre. The frame-rate cap here either isn't working, or is working in an extremely strange way.
This mode targets 45fps within a 60Hz container, a kind of frame delivery no man's land that reliably delivers judder as the game alternates between long and short frame-times. The only other time we've seen this is in the
truly horrible port of Arkham Asylum in the Return to Arkham Collection on Xbox One X, and it makes just as little sense here.
This puts the game in an uncomfortable place, as you're getting the visual fluidity of 60fps, but with graphical artefacts and more input lag than you'd expect at 30fps - not ideal for an action game, even on played on gamepad
My impression is that this is a PC-first release from developers that don't have a lot of experience developing for PS5, because a lot of the conventions and concessions that console games typically use just aren't here.
