Warren,
Thank you for your answer. I have an Nvidia card on my desktop with
Nvidia drivers which I think include OpenGL support. PyMOL is still
slow. How can I find out whether PyMOL is using hardware OpenGL or not?
Also, if I'm running PyMOL on a Linux server from, say, a Windows
desktop, do I have to have hardware OpenGL support in Linux or in Windows?
Thanks,
Simon

Simon,
Most likely you need to install vendor-specific OpenGL drivers to enable
hardware acceleration (Linux can't ship with them because they aren't
open-source). Refer to the web site for your graphics card vendor.
Without such drivers, PyMOL falls back on software OpenGL rendering,
which is much slower than RasMOL's more specialized molecule rendering
engine. With a decent OpenGL graphics card and installed drivers,
PyMOL's performance should meet or exceed RasMOL.
