I have a nVidia Geforce 5200 256MB. I had this same problem with KotOR, but that was a while back. When the game loads and it is time for the menu to come up I get a black screen. To fix it I went back to my original forceware 44.xx drivers. YUCK
Jedi Academy, Jedi Knight II and such are also unplayable. LA appears to have an OpenGL and older GeForce card problem.
Even Forceware 71.84 won't fix it. Note: UT2004 and Commando Demo and many other games work fine.
Maybe I should have brought it to Bioware's attention and Obsidian wouldn't have had to mess with it!
I'm hoping you guys have some idea!
Thanks,
