If you’re running this game under Vista or Windows 7 AND you’re experiencing stuttering gameplay (this may or may not be), you need to change some settings on the file:

Right-click on the .exe file, go to “properties”, then tab “Compatibility” and change the following settings:

• Tick box “Run this program in compatibility mode for”, and choose “Windows XP
  (Service Pack 2 or 3)”. Service Pack 2 might work better than Service Pack 3.

• Tick box “Disable visual themes”

• Tick box “Disable desktop composition”

• Tick box “Disable display scaling on high DPI settings”

Then, click “OK”, and start the .exe file. Now, everything should run smoothly…
