[SystemSettings] r.DepthOfFieldQuality=0 (removes ugly DoF) r.MaxAnisotropy=16 (Anisotropy x16) r.DetailMode=2 r.BloomQuality=0 (removes the really really bad Bloom) r.Tonemapper.Quality=0 (Vignette effects) r.SceneColorFringeQuality=0 (Chromatic stuff) r.MotionBlur.Max=0 (removes blur if game has it) r.MotionBlurQuality=0 r.DefaultFeature.AntiAliasing=0 (removes TAA if you dont want it) r.PostProcessAAQuality=0 (same as above) r.DefaultFeature.MotionBlur=0
going Ham
Also if You really really want to go ham I use this for NMH3 and Kena but A lot of these settings probably do things that arent even in this game Id recommend not using this one unless you really know what all of these do etc. Will increase GPU usage alot. and some of these might even make the game look worse a lot of settings are generally game per game bases
