[PyMOL] pymol crashes with large pdb files

Hi all,

I'm running pymol 0.89 on quite capable machines. When I ray-trace large
pdb files (proteasome; 1pma, 1ryp, 1fnt straight off the pdb), pymol
crashes. Doesn't matter if surface or cartoon representation. When I
decrease the number of subunits from 28 (or 42 in case of 1fnt) to less
than 20 (cut-open or end-on view), ray-tracing works fine.

Is there a limitation to the number of atoms or subunits pymol can handle?
I reset max_triangles from 10^6 to 10^7. Didn't change a thing.

Any suggestions? Just work on Ubiquitin instead??


Thanks

Andreas
