Baseline (Widescreen) Solution & Issues
Widescreen resolutions are native, but the vertical resolutions require the fixed exe in the attachment above as it renders in HOR- instead of Vert+ like the orthographic projection. For wider resolutions that aren't loaded in the selection list, change the resolution in the registry editor. The keys are the following:
ScreenWidth
ScreenHeight
Optional FOV:
To get a higher FOV you need to HEX edit the FGUY.exe in the attachment. From there, go to offset 5DB32E and change 00 00 80 3F to any higher value like AB AA AA 3F or 39 8E E3 3F - see Additional Screenshots. Custom fix also available from the PC Gaming Wiki Community Files (search there).
