The following registry setting manually changes the rendering engine from hardware to software, which should hopefully prevent the issue of black boxes covering the screen.
- Click start > All programs > Accessories > Run
- Type “regeditâ€, without the quotation marks, and click ‘Ok’
- Go to: HKEY_CURRENT_USER\Software\Bullfrog Productions Ltd\Dungeon Keeper II\Configuration\Video
- Then set ‘Engine Id’ to ‘4’ and ‘Screen Hardware3D’ to ‘0’
If you have other problems, go to Esoteric Articles and follow the instructions.
