[Chimera-users] OS X aqua version

[glenn millhauser]

Hi Tom and Eric,
   I ran the benchmarks on my macbook and sent the results to Help  
(and included below).  From my untrained eye, it looks as though there  
are performance differences.  From the user perspective, as I noted in  
the previous email, rotating the molecule in the aqua version using  
the laptop feels jerky.  However, I also did benchmarks on my imac,  
fairly new one with intel dual 2.8 GHz processors, and they are much  
closer to each other.  These were also forwarded through Help.
    I did not have the Model Panel open.
Hope this helps.
all the best,
g
