I've installed SFC III using the compatability program for Windows XP SP2. Game works perfect with Windows XP SP2. The game loads and plays accept for game lag when the cursor is moved. Mouse, Keyboard, and Video drivers are up-to-date. I believe it to be a DX problem since Windows Vista operates with DX10. The DX9 patch and (or) the 534b patch doesn't seem to work either. Since there isn't a DX10 patch available for SFC III yet, does anyone know of any other solutions to try? Game lag sucks!!! Thanks
Looks like I'll be playing SFC III on my Windows XP SP2 Laptop until a patch or DX10 solution is found. Thanks anyway to all.
