Unpack and copy the files in to your main Project cars 2 folder.
Set your exposure in the games settings menu to 1.80.
You will need to tell the game where your shaders & textures folders are by manually editing the d3d11.ini file. Don't worry, easy stuff, just open with notepad.
Once this is all done you should be enjoying a more natural set of colour tones with a very subtle cinematic effect without a hit on FPS. This filter makes slight alterations to sharpness, ambient light, Gaussian blur, bloom, vignette and the overall colour tone. Give it a try, I hope you like it.
Use SHIFT-F10 to open reshade panel to tweak further and it's the backspace key to switch effects on and off during play.
