I've done all this before, and I can assure you that MANY commands take less time to submit than they do to execute, especially if PCI is the bus. With 3D, we'll get lots of tiny triangles that are also faster than the bus. Packing is vital for throughput.
Your experience should be better. From the outside it is hard to tell how long the GPU takes to execute an instruction. That suggests a feature, an on-board timer that tracks how long the command stream runs and reflects pipelining. Then you could run various combinations of op codes and see which one is the fastest. Other overhead getting in the way makes this hard to measure. -- Jon Smirl [EMAIL PROTECTED] _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
