My AMD app setup:
Default settings with FSR4 on
Darktide set to the global profile
You do not want this
You can tell if FSR4 is working by looking for places where lines shimmer or objects smear. The worst case I’ve found of this is the particles in the psykanium against the metal grate in the center
FSR3:
The particles smear against the center metal grate and the grates further out shimmer. The crest on the floor on the bottom left also has shadows that wobble a bit.
FSR4:
Much better! There’s still a little bit of smearing if a particle goes along the grate at the right angle but it’s mostly not noticeable. The grates further out also look a lot less distracting.
