So I tried out ReShade with BeamNG. It is amazing! Excuse the terrible post-processing I created, It's just to show off some of the effects available! PC Specs: i7 - 2600 12gb ram GTX 970 Running at 1920x1080 The post processing hits performance incredibly hard depending on the settings/effects enabled, however you can toggle ReShade on the fly! If there's enough interest I'll write up a quick 'n dirty tutorial for ReShade.
