Michele, Did you just migrate from an older version? We switched PyMOL over to perspective-based rendering (WYSIWYG with OpenGL) as the default at some point in the past year. You can still render orthoscopically if you'd prefer:
load 1alk.pdb show surface set orthoscopic set hash_max=160 ray =>2.58 seconds on 2 X 2 Ghz opteron load 1alk.pdb show surface set hash_max=160 ray =>10.7 seconds on 2 x 2 Ghz opteron In other words, raytracing taking into account the perspective transformation can require almost 5X more time than orthoscopic rendering. FYI: on a quad-core G5 Quad 2.5 Ghz, the times are 1.78 seconds and 4.82 seconds respectively. Those Mac G5 Quads are PyMOL raytracing monsters! Cheers, Warren -- Warren L.
