My own attempt at a ReShade preset for DOOM 3: BFG Edition. The aim was to make a postprocessing preset that brings out the colours, enhances the contrast, and adds slight effects to lighting, while not making light colours sharp, and while retaining similar area visibility to vanilla (You can see areas without a flashlight where you wouldn't normally ned to use it and vice-versa) while also being somewhat compatible with DOOM 1 and 2. Occasionally the screen can freeze when reshade is on but still be running and be fine without it. This happens usually with an alt+tab and is caused by the game engine. Changing the resolution ingame fixes this. The settings text contains the SweetFX part, however most of the different frameworks are used, so you'll need to download the whole thing to get my intended look. This is also compatible with original DOOM 3. :)
This preset uses multiple files in the ReShade framework, therefore I cannot paste the entire configuration here.
