Hello,
Apologies for the somewhat naive and general question but I have tried
anything I could think of and I'm running out of options.
I was using pymol to ray some high quality images. The scene was quite
complex. The settings used were:
antialias 2
ray_trace_mode 1
stick_quality, 50
fancy_helices, on
with these settings I would ray 3600 and take approx 10mins to complete.
Two days later, after restoring the session from a saved .pse file, I was
trying to render the same images at a different orientation, exactly the
same settings. This time it took approximately 2 hours per image with a
rate of 1 frame/hour. At first I though it was the complexity of the scene
that had somehow changed in the new orientation but when I tried rendering
a simple cartoon protein structure, which would otherwise take seconds, it
now takes around 20 mins, same rate.
I'm on ubunutu 14.04, nothing else is running on my workstation and nothing
else is using the cpu. Interestingly, i tried using a different machine and
I'm getting the same slow rate.
Any ideas on what could cause this behaviour? I'm happy to provide further
info if necessary.
Cheers,
Nick
