Using the default, open source driver, very small graphical lag with desktop effects; this is expected since it's an older card. After a while, problems start to occur. Regular desktop use will cause more serious issues. Menus and bars disappear, windows will look solid-white and other graphical bugs occur. Shortly after this will cause the X server to stop causing the screen to go blank. I can usually run "startx" again, but the problems persist. Cinnamon 2D also did not work.
