Graphics Cards

[assiduous]

I'm suffering noticeable texture blurring in Assetto Corsa - note the blurring in the top and bottom tracks compared to the middle track in the first pic. Over on race department i'm being told this is dealt with on nvidia hardware by forcing tri-linear high quality texture filtering and 16x AF. I've tried forcing high quality texture filtering but other than a drop in FPS I can't detect any improvement. 16x AF does reduce & push the blurriness further away vs 8x, but as you can see in the second pic even with 16xAF the road lines degenerate into a blurred smudge not far past the start/finish line, and stop dead about where the other cars are visible. Is the blurring on black cat county and LAC the same for other AMD GPU owners out there or not? Is this potentially a driver issue?
