I was running into issues playing Starcraft 2 on Windows 7 (32 bits): once in a while, the game would unexpectedly quit with "Core: out of memory" as the error message. I went to the Blizzard support forum with this problem, and they told me that my video and sound drivers are outdated by a year or two.
Notwithstanding that I'm not sure how these drivers can impact the memory usage of the game, I don't know if upgrading is a good idea. I'm quite sure that it won't hurt the Mac OS side of my computer if I do (as the Blizzard rep suggested to double-check), but said drivers seem to come from Apple, and I'm not sure if my Mac would behave well if I upgraded them.
Has anyone tried to upgrade the sound and video drivers for Windows 7?
