by the way these shadows appear on all tracks not just custom made ones i also noticed since the update that fences that used to cast shadows the correct way are now solid shadows
This bug is NOT about the flickering, lkook at the pic in first post. To the OP: Try shadows on high instead of MAX, works for me.
Been having this graphical problem, i have recently downloaded nvidia 30.59 beta drivers that seems to have fixed the problem. i only seemed to get them weird shadows in high or maximum shadows, now i can have them on maximum with no problem.
