61	Rendering takes minutes, Mac Nvidia Geforce GT 330M graphics	Tom Goddard	Tom Goddard	"Using the lab Mac laptop (mid 2010 model) with Nvidia Geforce GT 330M graphics (512 Mb) gave extremely slow rendering of molecules in sphere style.  I opened 1jj2 100,000 atoms and the machine was frozen for about 3 minutes before it rendered.  Then it appeared to try to render again maybe from my previous mouse click where the Apple System menu covered part of the app and took another 2 minutes where the machine was unresponsive.  When I was finally able to quit I restarted and tried 10,000 atom 1mtx.  It opened in about 30 seconds.  I turned on ambient occlusion (command light soft) and it froze the machine for another 3 minutes.  It eventually did display correctly.  I rotated the model which took about 15 seconds for one step.

We will need to detect this kind of slow software rendering so old machines are not frozen by the software.
