Jip is indeed talking about Reshade, which I personally use to increase the color saturation and sharpness of the game slightly.
You can get it here. https://reshade.me/
Make sure to direct it not to your steam directory, that will only affect the graphics of the game when you play it via steam. You need to direct it to the copy of Forged Alliance that FAF makes, the path should be C:\Program Files\Downlord's FAF Client iirc
Thanks. I found this https://www.moddb.com/mods/loud-ai-supreme-commander-forged-alliance Is this MOD compatible with FAF client?
