Re: [PyMOL] Slowwwww ray

[Stuart Endo-S. <stu...@du...>]

Default view, white with black background (sticks):
Ray: total time: 15.68 sec. = 229.5 frames/hour. (15.68 sec. accum.)

Surface ray (white w/ black background):
Ray: total time: 32.67 sec. = 110.2 frames/hour. (48.35 sec. accum.)

About the times I've been seeing for equivalent work I've been doing.  
Different system but your times don't sound too different from what I've seen 
on our dual-G5 2.0 GHz with an older Radeon card.  I'm running an Opteron 150 
(2.4GHz) with 1GB DDR400 ECC registered and an MSI FX5700 LE on FC4.
