Baseline (Widescreen) Solution & Issues
Most common widescreen resolutions are listed in-game. The list is pre-determined rather than detected from the system; custom/unlisted resolutions can be set in Darkmod.cfg (see Resolutions for details).
FMVs, the HUD and all 2D elements stretch from 4:3.
The game must be restarted to change resolutions. Choosing a different aspect ratio without restarting will make gameplay stretch incorrectly.
