Greetings, It is my pleasure to announce the release of open source PyMOL v1.5.0.1. The source code has been committed to the open-source repository. It is revision 3976. An svn tag and downloadable bz2 source file were also created. All of this is accessible form the PyMOL project page on SourceForge (http://sourceforge.net/projects/pymol/).
Before upgrading PyMOL -- please -- upgrade your video drivers! NVidia and AMD/ATI cards are known to work well. But, Intel Mobile and other low-end cards might have issues with the new rendering. The majority of rendering anomalies are fixed by simply upgrading your video drivers. You should be able to pull and build just like normal. You will need Python 2.7. Some simple testing on my Linux machine shows the following improvements in real-time rendering performance for a large protein (58,000 atom Gro-EL, PDB 1AON) with the new open-source PyMOL code: Lines: 240% increase (81 FPS to 270 FPS) Spheres: 864% increase (28 FPS to 270 FPS) Sticks: 2100% increase (8 FPS to 180 FPS) Cartoon: 3757% increase (27 to 270 FPS) Surface: 2600% increase (10 to 270 FPS) Mesh: 33% (180 FPS to 270 FPS) Your numbers will be different. This Linux machine has a powerful card used for development (http://www.amd.com/us/products/workstation/graphics/ati-firepro-3d/v8800/Pages/v8800.aspx). It was generously donated by AMD. If you use an AMD/ATI card and PyMOL works for you it's because AMD/ATI helped out. You may want to thank them. What I've seen is that the more powerful your card the greater the _difference_ in speed. That is, low-end cards should see improvements in the range of tens to hundreds of percent while more powerful cards should register improvements like mine, in the thousands of percent for some representations. To quickly test performance of the new code on your machine just load a large structure (eg. 1AON; 3R8O and 3R8T) and quickly rotate/translate it. To see the refresh rate, type "set show_frame_rate". The refresh rate shows up in the lower right hand corner. Compare the frame rate, smoothness, and rendering quality when the setting "use_shaders" is turned off and when it's turned on. Compare different representations, each time turning on and off the "use_shaders" setting. You can quickly update old PyMOL session files to the new rendering by clicking, Settings > Rendering > Modernize after loading the old session file. PyMOL will flip all the right settings to update rendering. If the new code doesn't render properly, you can revert to the old style rendering by typing: set use_shaders, 0 set sphere_mode, 0 Please let us know how it goes.
