RT is increasing the CPU usage a ton. Also consoles sucks at RT so its definitely the issue. RT has a huge cost especially on console. Turning that shit off would result a better resolution and much closer fps to locked 60
I don't think it's the issue.
you can have scenes in this game with large vistas, vegetation everywhere, distant rock formations etc, and run at a locked 60fps on Series X.
but then you go into the first open hub area, with arguably the same amount of detail, and suddenly 30fps with stutters every other second.
to me this seems clearly like the game having issues loading too NPCs, enemies and interactive objects.
because as soon as you look at a just as detailed backdrops, zero framerate issues or stutters
turning RT off would help, but it would be just a small bandaid on a gigantic wound that is the terrible CPU optimisations
