I know it exists, but I can't seem to find a list of startup switches to plug into the WITPAE short cut. Had to get a new pc and now attempting to reinstall WITPAE.
The list is in the Read Me file in your game install location.
Info on when/how to use them is well covered in the stickied thread on slow performance. The Seabee utility that Korvar created is designed to set up the switches for you without having to do the exacting typing and pathing in the Shortcut to the game engine.
