  • 1 - Minimum Quality.prs
    • If you want to get the MAXIMUM FPS possible in Doom 3, use this preset. It's useful if you're playing on a very old machine. Note: some textures, texts will become unreadable.
  • 2 - Low Quality.prs
    • Using this preset gives you more FPS. The different between the Minimum Quality preset and this preset, is that the Gun is shown in your hand, and the texture quality is slightly better.
  • 3 - Maximum Quality.prs
    • Use this preset if you want to boost doom3's graphics to the highest level.
  •  Set everything to default.prs
    • This preset sets every setting to it's default value.
  • Doom2 style.prs
    • This preset gives Doom 1-2 like gameplay. It will incrase the running and walking speed, speed up the time by 10%, and incrase the brightness. The gun will be showed in the middle also. 
    • You must execute the configuration file generated by this preset, after every mapload!!
