Solutions & Issues

Baseline (Widescreen) Solution & Issues

Native Hor+ support with comprehensive settings.

Field of View: VFOV 60-90. Does not affect weapon models. The higher the FOV, the weaker the scope/sight zoom-in.
Aspect Ratio can be set independently of resolution. Leave it alone.
Widescreen Letterbox adds black bars to a 16:9 picture. Don't do it.

Ultra/Super-Wide (21:9/32:9) Specific Solution & Issues

Native Hor+ support. Oddly enough a number of art assets were designed with 21:9 in mind, but not the HUD.

32:9 support varies from update to update, going from fully supported to pillarboxing.

Eyefinity / Surround Specific Solution & Issues

Native Hor+ support, HUD is automatically 16:9-centered.
