The odd thing is that the viewer is using threads to fetch and decode  
textures. There's actually a thread just for image decoding. That  
doesn't mean that this is making best use of the existing cpu on your  
machines though but, it should...

One way though to turn the entire viewer into a single threaded app is  
to turn MEM_TRACK_MEM to true when building. This define is supposed  
to be used for tracking memory leaks and the like (if I'm reading the  
code correctly). It's not turned on in the svn repo but, in any case,  
if you are building your own viewer, you may want to check this just  
on the outside chance it's turned on.

Cheers,
