Re: [ccp4bb] slow graphic in mac 10.6
Hey Rui, for what it's worth, I had a very similar problem. I upgraded a MacBook Pro to OSX SP6 and got extra-slow graphics and a wildly flickering PyMOL window - only on the laptop screen, though. On the external screen, PyMOL looked ok. Ray-tracing was painfully slow in either window. When I cloned the screen instead of extending it, the flicker disappeared and didn't return when I went back to the original setup of two contiguous screens. All is good now. While this is by no means an answer to your question or useful advice, it means at the very least that you might be able to overcome your problems by fiddling around. Good luck.

Since then, I noticed that when I open a terminal , it's very slow and if I type glxgears, it only shows about 1400 FPS. If I open pymol, I can actually see the images are flashing. Does anyone know why? Thanks a bunch. Rui -- Andreas Förster, Research Associate Paul Freemont Xiaodong Zhang Labs Department of Biochemistry, Imperial College London http://www.msf.bio.ic.ac.uk

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 For what it is worth (I'm fairly confident that indeed this is not the cause of the problem you are seeing, but better checking than missing the point): The current MacBook Pro also have two GPU, one integrated in the chipset and a more powerful dedicated one. By default only the chipset integrated one is on (to save on power consumption), so if you're doing graphics it is worth going in system preference - energy saver and at the top preference window check that Graphics is set to Higher performance... A bummer is that it is currently necessary to restart one's session to go from one setting to the other, and I'm not 100% sure that this setting is preserved upon reboot of the machine...

Re: [ccp4bb] slow graphic in mac 10.6
Serge, this might indeed be the problem for some, but my MacBook is of an older vintage and only has one GPU.

Re: [ccp4bb] slow graphic in mac 10.6
Dear Rui: Did you by any chance install an old ppc version of X11 onto an intel machine? If so, it might be running via Rosetta, which is an emulator provided for transition, but could account for lousy performance. OS X 10.6 comes with X11 installed by default, so you might have clobbered it with something else if you installed X11. If that is the case, simply reinstalling the X11 on the 10.6 install disk should fix your problem. Also, run the command file /whatever/path/to/bin/coot-real If it returns Mach-O executable ppc then you need to use an intel-compatible coot for best performance.
