The first screen looks ok. Road looks too blue in second screen, doesn't look natural. I think it's hard to achieve significant improvement over rF2 default post FX settings. It was different few years ago when rF2 used to have that oversaturated look and dark lighting, now the defaults are good already.
I am more interested in any AA or texture improvements. The tones can be adjusted as you like, but the whole package would be worth installing and using if it helps with shadows, jaggies, transparency issues, etc. I don't know what, if any, of those long-standing graphics problems in rF2 this could address?
