- When you find it, just double-click on the file to open it in Notepad.
- Scroll down the file until you find the Graphics Options
- Under the last line ("last line" as in the last line of the list of entries under "Graphics Options", NOT the last line of "swkotor(2).ini"), add "Disable Vertex Buffer Objects=1", without the quotes.
- Goto File, then Save.
They shouldn't mess up a normal installation on their own.
Beyond that you might as well contact LucasArts customer service because I know next to nothing about the changes that they made to the collection.
