Baseline (Widescreen) Solution & Issues
Ultra/Super-Wide (21:9/32:9) Specific Solution & Issues
Cutscenes and most conversations are pillarboxed to 16:9 for both 21:9 and 32:9.
HUD isn't centered for 32:9 and you have to adjust the Safe Zone Adjustment in Settings > Graphics, to make the objective text appear completely on screen. This is limited to 90% so you can't put in any position you'd prefer. Screenshots below in Additional Screenshots.
