dang it! i guess i'll hang back with the 10.5 drivers since they work well with Borderlands. With 10.6, Borderlands exhibits a major problem akin to a memory leak. After around 30 minutes of playing, Borderlands will minimize itself down to the taskbar and windows 7 will display a message saying that this application/game has a problem etc... When I checked the list of running processes in task manager, it showed Borderlands as using almost 3GB!
