Fantastic work stf999!
I've been trying it today and loving it.. but I'm experiencing a problem. I'm getting an artifact on the car shadows, the traffic window and on the fence, they should normally be this kind of mesh/transparent texture, but it's artifacting and showing a white polygon instead. Attaching screenshot. It only happens in certain areas, in the beginner circuit it happens most notably near the pit entrance, but there are other two shorter instances elsewhere.
I've tried modifying most of the options in the INI file and also on Nvidia's control panel, but no success. Any thoughts?
