I created a guest account with no internet connection. No background programs. Only the most basic of screen environments. And only the required processes for Windows XP running. I named the account Real Flight and when I use the Real Flight RC 3D simulator I use this account. Doing it this way I can devote the maximum amount of system resources and graphics capabilities to running this program. It works but expect youre Eee PC to run hot and use the battery up in half the normal time.
