However, I get a lot of choppyness in the display. I have OpenGL vsync set using the nvidia-settings utility as well as in my .bashrc environment variables. When I run the demo I get the same results with sync to vblank on and off. How are you guys seeing it? Is it silky smooth or are you getting choppyness too? No choppiness here, nvidia 8800 GTS + 190.29
