This causes World of Warcraft for mac to not be able to keep up when capturing in-game video at high data rates (200+ MB\/s), which of course is the only way to get large frame size *and* high frame rate :) It took me literally years to finally think of this solution, and after a lot of fine tuning, it works great! The basic idea is to capture video files to a ramdisk and continuously move them to my RAID array during capture.
