You'll want to fine tune the in-game visual settings to suit your monitor settings on top of the reshade settings.
Just a forwarning, the AA in PCars2 is even worse than in Forza 7. It's almost impossible to eliminate it without running Ultra Supersampling and full AA. Enabling supersampling kills performance. Even with Ultra supersampling and AA as high as it goes, the game still runs into aliasing issues because the heat effects in the game are rendered at a lower resolution than the rest of the game when playing at 4K. Unfortunately these heat effects can't be turned off and are always emanating from your car. I don't ever remember seeing heat wash flowing from my car's hood, it must be really hot where SMS is located.
Expect performance to take a shit. To get 60fps on my old 980ti I was running 1080p with no AA with these reshade settings. At 4K it just said fuck you and gave me about 10fps
. On the 2080ti I'm getting a more consistent 60 @ 4K, but absolutely not a solid 60. With reshade off I have no issues. Don't even bother with any of the AO reshade options in this game. They tank performance and don't act like you'd expect. With a full field of AI and a thunderstorm going, I typically drop my to resolution to 1440p if I want to use these settings and keep any semblance of a steady framerate.
Anyways, here's the settings I'm using.

In movement the improvement is much more apparent. as the intensity of the lighting changes is dependant on the surroundings. Driving out of shadows into the sun will temporarily wash out the screen now before the adaptation kicks in and dims the lights.
Fine details are greatly improved (water droplets on the car are visible from further away, grass blades are more clearly defined, asphalt doesn't fuzz out, etc) and color saturation is reduced in dim lighting while enhanced in direct light (great for metallic paint). The ambient light pass acts almost like a type of bloom, but doesn't look like a piss filter, and almost comes out looking like actual bounce lighting. Strangely, the FXAA and SMAA passes accuentuate some of the fine details like mesh grilles, where typically AA passes make things blurrier,
