Well here's an interesting twist; when I log into X/Gnome as root, the games run a heck of a lot smoother (note that su/sudo doesn't have the same effect, I really have to login as root). Quake 4 went from 10-20 fps in the first level to 40-50 fps on average. I'm guesssing however that playing games as root (online games, that is) might not be a good idea. Now I just need to figure out what exactly makes games run slower for non-root users.
