No, I am pretty sure rendering is working ok otherwise. Using the mesa nv driver (software rendering), is very slow when there are lots of heavy graphics on the screen, I have to pretty much stick to anti-aliased lines. However, using the nvidia driver (direct rendering), it is much, much faster and I can have complex molecular surfaces or rendered bonds with no slowdown in rotation/manipulation. Plus, I do this with SGIs connecting to other SGI machines. Then the only limitation is the network connection.
