The Dark Messiah of Might & Magic Tweak Guide is here to help people resolve their issues with this game and to get it to a playable state as quickly as possible. There are several differences between the way the Source engine works in Dark Messiah and other Source games, so I've retested all the commands originally found in my Half Life 2 Tweak Guide, added several important new ones unique to Dark Messiah, refined descriptions to be clearer, and grouped together at least a dozen commands which can help reduce stutter. Also included are a range of specific troubleshooting tips for known bugs, and of course details of all the in-game settings and what they actually do in terms of performance and visual quality.
