Just realized there must be some benchmarks on chimera's webpages, and I found them. :) Glad to provide the benchmarks from my systems. Benchmark 1: Computer: IBM T41 Graphics Card: ATI Radeon mobility M7 (32M?, not 100% sure) CPU: pentium-m 1.4GHz System Memory: 512M OS: Ubuntu GNU/LINUX 5.10 Driver for video card: the built-in open-source radeon driver from Xorg-x11 6.8.2 Chimera: version 1 build 2176 Benchmark scores: surface 147 mesh 127 contour 133 solid 128 recolor 68 Benchmark 2: Computer: HP XW5500 workstation Graphics Card: ATI FireGL 8800 (128M memory) CPU: pentium-4 2.4GHz System Memory: 512M OS: Gentoo GNU/LINUX Driver for video card: ATI fglrx driver 8.14.30 Chimera: version 1 build 2176 Benchmark score: surface 234 mesh 227 contour 142 solid 256 recolor 107 Something is confusing me. As you see that scores from benchmark 2 are higher than scores from benchmark 1. But in case that I want to save a protein structure as a png file, the rendering in system 1 is nearly two times faster. How can this happen? Best, Mingfeng Yang
See if the 8.18.6 drivers make a difference on system 2

Tried it last week. Finally, what I found out is that actually the non-proprietory driver from freedesktop project provide even better performance, so I just gave up ATI proprietory driver. Sabuj Pattanayek wrote:

Hi Mingfeng, I added your Chimera benchmark scores to our web page. http://www.cgl.ucsf.edu/chimera/benchmarks.html The updated page won't appear on the web site until tomorrow. The benchmarks just measure the graphics card (surface, mesh, solid tests), the bandwidth to the card (recolor), and the CPU speed (contour). The time to save a PNG image might be limited by disk speed. Or if it is taking a long time for all the tiled images to flash by that is controlled by a particular graphics card feature -- drawing directly to the front buffer -- that none of the benchmarks measure (they all use "double buffering"). Thanks, Tom
You really should use the ATI graphics driver instead of the non-propreitory one. Some stuff will benchmark better with the non-proprietory one, but the overall quality and speed, across all of OpenGL features, will be better with the proprietory one. The benchmarks only measure speed. - Greg On Sun, 23 Oct 2005, Mingfeng Yang wrote:

I had a completely different and unhappy experience with my FireGL 8800 card. Really, the non-proprietory driver give me better performance. A simple comparison is, glxgears give ~2700fps for non-proprietory driver, but only ~1600fps for ATI fglrx driver. I did all possible tweaks for xserver configuration (xorg.conf); ATI driver always lose. I know that glxgears is not for benchmark, but it's the same machine. Rendering a picture with non-proprietory driver is also faster. Probably the bad luck is just for FireGL 8800 card; hopefully other higher end card will do better. Mingfeng Greg Couch wrote:
