[Openmcl-devel] OpenGL Performance PPC vs Intel-Mac 32/64

I did program x86 chips at the assembly level about 30 years ago. This  
is all part of suppressed memory, now. Anyway, not to worry. No  
followup question. It just sounded as if there were  some kinds of  
trade offs made between  86-32 and 86-64. The tradeoffs were not clear  
to me. I will accept things how they are. For applications of OpenGL  
this is somewhat bad news as indeed the individual calls usually take  
very little time compared to the overhead. However,  direct rendering  
with OpenGL, one vertex at a time, is no longer recommended anyway. I  
guess the consequence of all this is simple to accelerate the process  
of phasing out direct mode code.

Time to move on to more important things. Have you been able to get  
Cocotron to work with CCL win at all?
