I just installed windows XP on my macbook. I then downloaded and installed the latest intel GMA 950 graphics driver. After the little program ran, the screen went crazy with colorful lines in it so I got scared and restarted. However, after I restarted, the graphics were fantastic in windows. I then restarted to 10.5.1 leopard and to my amazement, everything looked better in mac osx as well. The widgets came in smoother, the dock looked more reflective, the menu bar looked more transparent, and games ran much more smoothly. I also ran Xbench openGL test and the frame rate had gone up from 294 to 370. Do drivers in windows effect drivers in Mac OSX? If they do, I had no idea. My specs on my macbook are Intel Core 2 Duo 2GHz, 200GB HDD, and 2GB of RAM.
