i can't find QualitySettings on that file, i do find it in global-metadata.dat and globalgamemanagers.asset (with extension) tho. On globalgamemanagers (without extension) i found a bunch of strings for FXAA.
but i'm stuck at figuring out what to edit and what to input hahaha. Googling around for 15 minutes didnt help me. I'll google around again.
EDIT: yay! i think i found the options. Gonna do some test later after work.
Bummer. I though I found it but it didn't work.
Using unity asset explorer I can open globalgamemanagers and change a bunch of stuff
Lights and shadows can be changed and applied. Background color can be changed and applied.
But resolution despite already chabged to 3840 and 2160, it stays the same in the game
As for anti aliasing, there were a bunch (smaa, fxaa, taa, msaa) but I have no idea what to change hahaha
