Topic on Talk:Clive Barker's Undying
This information here is bad.
1. First off, if you're using a patched .exe, as in any of the Widescreen fixes, no matter what you do - DxWind will no longer boot the game, even with admin rights / compatibility mode. I couldn't get it to anyway, and certainly not with the instructions provided.
2. The goal here is more easily acomplished by simply marking the following System.ini settings, under "[WinDrv.WindowsClient]":
StartupFullscreen=False
Or, you can simply use ALT + ENTER and it'll do the same.
