Baseline (Widescreen) Solution & Issues
Only some resolutions are supported. It's easy to find threads about lack of resolution support in the Steam forum for the game.
On my system, even with the desktop set to 1400x1050, I had no 4:3 resolutions available to me. I only had the following resolutions available to me:
1280x720
1280x1024
1440x900
1680x1050
1920x1080
All 4:3 screenshots in this DR are actually 5:4 1280x1024 for comparison purposes.
