Scott,
Not at all. The only way to increase ray tracing speed is to
upgrade your CPU. I think a 100-150 Ghz Pentium 8 is just about
optimal.
You can also tweek some of the parameters:
Increasing the hash_max setting to 160 or 180 can improve raytracing of
complex scenes, if you have lots of RAM.
Disabling shadows (set ray_shadow,0) will speed things up.
Hiding lines is important, if you can't see them underneath other
geometries anyway.

Subject: [PyMOL] Will a faster graphics card speed up ray tracing?
Warren,
Does PyMOL ray tracing speed depend on the graphics card? I am
curious
what factors (hardware or software) effect rendering speed.
Thanks,
Scott
