Warren, Does PyMOL ray tracing speed depend on the graphics card? I am curious what factors (hardware or software) effect rendering speed.

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. Warren -- mailto:wa...@de... Warren L.

On this note, our collaborators in CS have a test Itanium2 box that I have an account on - I've been planning to try out a bunch of comp. bio. software on it (and compare with the Xeon, Athlon, R14k, G4, etc.). PyMOL is definitely included in this. Would the results be of interest to others on the list? ---------------------------------------------------------------------------- Nathaniel Echols Programmer na...@bi...

I have some old Itaniums (actually, 8 dual Itaniums), and I'll be happy to try PyMOL on one of them.
