Q: How do I improve Illutia's performance on Windows Vista/7?

A:  Turning off the Effects in Vista and Windows 7 can greatly improve performance. This is HIGHLY recommended on slower computers to play any game not just Illutia.

1. Click Start, and then click Control Panel. 2. Click Appearance and Personalization. 3. Under Personalization, click Change the color scheme. 4. In the Appearance Settings dialog, click Windows Vista Basic, and then click OK. Or, if you prefer a Windows 2000-style interface, click Windows Standard, and then click OK.
