... and to help your performance out a bit, open the task manager (ctl/alt/del) and shut down some of those processes that aren't doing anything but wasting resources...
... if you've got qttask.exe, realsched.exe, that ipod iTunes crap running... just shut em down... either from the task manager, or the task bar at the bottom of your screem...
don't shut down everything now... just the processes that you know you surely aren't gonna be using during a SHIII session...
that should help a bit...
good hunting
