I have done a lot of searching and reading about various graphics problems people are experiencing with their 17" MBPs, and it seems mine just started with the choppiness in the last few days. Expose, Dashboard, games, all run horribly and stutter and chop constantly. It's maddening how a brand new machine with 256 MB of VRAM runs far worse than a Rev. A Powerbook from 2003 with 64 MB of VRAM. Can anybody suggest a fix or something they did that alleviate the problem? Or is this simply a driver/software problem and we are stuck hoping that Apple addresses it with 10.4.11?
