[Chimera-users] benchmark results 1.2422-linux_x86_64

[Greg Couch]

Are you sure there aren't any 32-bit shared libraries loaded?  Because if 
there are, then you will save a lot of memory by using the 32-bit version
of chimera.  Also the 32-bit version of chimera is faster because it pushs 
around less memory (the data structures are smaller).

The benchmark scores are inline with what one would expect from an 
integrated graphics solution.  If you want higher scores, you need to use 
ATI or NVidia graphics.

And yes, chimera is not multi-threaded.  There are some computations 
within chimera that would benefit, but the most benefit comes from when 
OpenGL is multi-threaded and the newer graphics drivers are (NVidia, 
Apple today, more coming).
