There was a guide around that would help you get as much out of your system you could, but I have no idea where that went or where to start looking.

Basically, don't have any programs running besides RTW. This includes things like antiviruses and internet downloads. Also set RomeTW.exe to High Priority. Also if you have a dual core, set affinity of RomeTW.exe to only one of the processors.

I go into Task Manager and close all programs that don't either start right back up, aren't allowed to be closed (end in ...ss), or will crash the computer (explorer.exe, System, System Idle Processes, svchost.exe).
