while on my dual 867 powermac a simple gl application is running fine, on the powerbook (1,25 ghz, 512 mb ram) of a friend it’s not acting smoothly.
it’s exactly the same code and system configuration. any ideas, what’s the cause? thanks in advance!
There’s a rather large difference between a dual 867 powermac and a 1.25GHz powerbook. I certainly wouldn’t expect anywhere near identical performance characteristics. It seems unlikely they even have comparable video cards, and they certainly don’t have comparable amounts of L3 cache.
Apple provides excellent performance tools for finding these sorts of problems. The OpenGL profiler and OpenGL driver monitor will tell you precisely where your graphics card time is going, and Shark will tell you precisely where your CPU time is going.
