Please use Chimera's Help / Report a Bug dialog to file this as a bug, 
and, if possible, give the PDB id of the 80S ribosome you are trying to 
view.  That will tell us about your computer and the size of the 
structure you're trying to view, and that will enable us to give a 
better answer.

So, my guess it that you are trying view a structure that is too big for 
your computer to handle quickly.  So the solution would be to increase 
the physical memory.  You may also need a graphics card with more 
memory.  Another possibility is that you are reading in the structure 
using the mmCIF reader -- in Chimera, the mmCIF reader is slow and the 
solution is to use the PDB format version.  Our Chimera successor, 
ChimeraX, reads mmCIF files very quickly and can handle large files with 
ease.  Unfortunately, ChimeraX is not yet available.
