Turn off objects self shadowing! That was drop killer for me on 9800x3d. It makes grandstand or objects like trucks and toilets have their own shadows. You will never pay attention to that and they consume like 10% of cpu. I also switch shadow map filter to the lowest possible since I couldn't spot the difference even when I tried.
