I have some laggy movement of the background screen and of tux when i turn left or right, while the whole game runs perfectly -even during the laggy movement the framerate is big-
It's not a low system problem -i got a i7 core, 8 gb ram and radeon 5850-
Is there some option i should check? I tried to lower even resolution to 800x600 -i'm actually playing 1680x1050- but the laggy movement is still there.
Actually, this lag stayes even with a clean installation.
