Definitely both of these things. I'm on Ubuntu with open source nvidia, so nothing is hardware accelerated yet.
I'm really hoping that the combination of Nouveau with 3D support, Cairo-GL and Pypy will speed things up significantly for shoebot, some time in late 2010/early 2011.
(For the asynchronous part I'm going to be trying python multithreading with a queue so that the rendering doesn't happen in the main thread).
