There is a bug in the representation of the shadows after dark (9:00 pm) in the Monte Carlo circuit, as shown in the image. View attachment 586 The shadows appear on the wall. And another thing, I have very few FPS even though my GPU is very new(Battlefield 3 on my computer works al 60fps), I hope resolve performance problems.
