[Chimera-users] Benchmarks

[Greg Couch]

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.
