HI,Dear All, sorry for this non-crystallgraphic question, but I think people here may know how to fix this problem. Several days ago, I posted a question about slow coot in my mac and people suggested me change some settings in coot which does help. However, I still feel something is wrong. I noticed the slow speed when I installed x11,( I switched from ppc to macpro and need to reinstall x11 and coot etc ). 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
