Those settings appear to be what I've been using for a while, with the exception of running AF at 16X in NVidia config. For whatever reason, I find the native AF in AC to be more pleasing to the eye.
Setting the FOV exponent at 0.5 was the thing that got rid of flashing triangular areas in the sky for me (which were particularly noticeable on replays). That had been bugging me for ages before I changed to that setting. And those far plane adjustments did seem to help with shadow cascading on cockpits and drivers too. I've also tried 40000, 60000 as an alternative, but I was undecided if that was even better, or just placebo.
What does that FOV exponent do? My setting was at default on 2 and I have been having flickering shadows on certain tracks. I am not at my gaming computer so I cannot test it but do you think it would affect those as well?
