That's why Aven is slow and flickery - your OpenGL stack is rendering in software. Aven currently redraws more than it needs to as well, which doesn't help - hopefully I'll fix that soon. You probably need the nvidia drivers from non-free for good 3D performance - the Debian wiki has details on how to install them: http://wiki.debian.org/NvidiaGraphicsDrivers#non-free_drivers Cheers, Olly
