POE2 - Xbox - Couch Coop - Grass in Hunting Grounds triggering dynamic resolution

Issue:
- enter act 1 Hunting Grounds
- graphic settings:
- dynamic resolution = true
- render resolution = no upscale - 3840 x 2160
- upscale mode = NIS
- the grass in this area triggers the dynamic resolution feature and dropped resolution to seemingly the lowest quality and framerate dropped to around 10-15 fps.
- basically an unplayable map, the grass creates an almost undulating noise like pattern.


A work around that I found is to set the upscale mode to FSR. This reduces noise and smooths out the FPS.

Xbox Series X
PoE2 0.1.0b

Why cant we run the game on 120hz when got monitor and Xbox Series S/X that supports it?.
