I've had my copy of GC2 open playing a large game since 1.1 came out. Over the last few days I've noticed alt-tabbing back and forth was taking progessively longer. Finally after the last time I tabbed back tonight I saw a note that windows had enlarged my page file. Task manager showed ~5-600mb in use by various processes (GC2 ~- 300m) and a commit charge of 2.4gig. I exited the game, commit charge dropped to 600m. Resumed it, taskman lists GC2 at 680m and commit charge at 1.3g.
PS, as an asside, why does the total memory listed in the process tab of taskman rarely equal the number listed under commit charge?
