Hi Vitali, For the new graphics/performance you want set use_shaders, 1 not set use_shaders, 0 But, on your card if you get better performance the feel free to switch back to the old rendering. What does PyMOL output on the console when you start it? Please copy that into an email for me. Ch

Jason, I do not have .pymorc file. But when I set "use_shaders" to 0, then everything becomes fast and nice. I guess I just can turn on shaders only as the final step before ray_tracing. Thanks for help, Vitali On Thu, Feb 16, 2012 at 1:22 PM, Jason Vertrees < jason.vertr...@schrodinger.com> wr

Hi Vitaly, It looks like the 7150M has only 57 megs of dedicated memory. Once you exhaust that your performance will decrease dramatically. I'l contact NVidia and see if they have any suggestions. Also, do you have a ~/.pymolrc file? If so, what's in it? For the new graphics to perform, you need

Hi, I recently installed a new version of licensed pymol 1.5. It works ok with small molecules (<25 kDa). But, unfortunately, I found that after I load relatively large molecules (>60 kDa) everything really slows down, movements become somewhat abrupt and etc. At the same time, I can open this mol
