Yes, I have seen DX in Windows seem to lag when I am letting my app run as fast as possible with no throttling. It is wierd, because it does it on my PC at work while running about 400fps, but then at home running about 650fps it does not lag.
Anyway, I switched to the OpenGL driver and everything is fine on both machines and it runs about the same speed.
