That would imply to *me* that you've been wrong all along with your CPU-bound argument, unless it's only Quartz's 3D and transparency elements that are handed off. Your description of anything graphics-related being wholly CPU-bound sounds wrong to me, from the way I understand the Windows graphics subsystem to be interacting with graphics hardware. I was only describing the Mac side of things as the implications of what you've been saying about graphics cards, instructing Tyler at length on how his own computers are working (despite the evidence of his own in-person hands-on experience). For what it's worth, I think Tyler has plenty of reason to become testy with you -- you seem to be arguing in a manner that ignores any point he makes that goes to the heart of the dispute, while insisting that certain things are true in the face of his providing evidence that clearly shows that they are not. -- David W.
