And a 2560x1440 resolution mod for version 2.1.0...
Xenoblade 2 v3.0.0 All-in-One Graphics Pack
The graphics patches have now been ported to Xenoblade Chronicles 2 update 3.0.0 and combined into a single all-in-one package.
Each version includes the resolution patch, disabled dynamic resolution...
My changes on the ini + another changes i got from this thread (for emulators, im using Eden). Best paired with 2x resolution on emulator, the exefs doesn't have supersampling 2x.
ColReduction= off
-personally I didn't noticed any difference...
