[PyMOL] Slowwwww ray

[Michele F. <mfu...@me...>]

Hi,

I have a 2GHz G5, 6GB RAM, running OS X 10.4.3 server.
I started doing some modeling after about 6 months hiatus.
I'm using MacPymol 0.99b29 (no flickering with this).
But....
it's slower than molasses. I get:

  Ray: total time: 16.16 sec. = 222.8 frames/hour (32.15 sec. accum.).

This is simple white surface on white black background, nothing  
changed from default.
It a fairly small molecule, 600 resi, 5400 atoms.

My card is the stock ATI Radeon 9800 Pro.
Could it be I messed up something with OpenGL?

Why is it so slooowwwww

Thanks

Michele

PS: would anybody with a similar setup try 1ALK.pdb show surface in  
white and tell my the time to ray?
Mine is:

Ray: total time: 25.45 sec. = 141.4 frames/hour (57.60 sec. accum.).
