Has anyone doing 3-d modeling and rendering found that the MBP video card is not fast enough. I loaded a model of mine into the apple stores MBP and changing views of my model in wire frame was choking the computer. Is that a software problem or a hardware problem (VIDEO CARD)? Also any tips on what you have done modification wise to MBP so that it works for you as a 3d modeler and renderer would be appreciated.
