I, too, am having the same problem running KOTOR II on a laptop with the ATI Radeon Xpress 200M...same as PacMan, I get erratic movement key responses that make the game unplayable.
I keep seeing those saying, "well, you cannot run it on a laptop because the laptop has onboard graphics that share resources..."
But! As the laptop users keep trying to point out: these laptops run many other 3D and high end games with no problems! (Battle for Middle Earth; Neverwinter Nights Platinum, Medal of Honor Pac. Assault, and many other games run great on this laptop).
Also, as others have pointed out this ATI 200M has 128MB dedicated Ram...yes, it has it's own ram and doesn't steal it from the motherboard!
I'm sorry...but with a large percentage of the problems being posted by ATI users, and then it seems the ones that have no work around are the Laptop users with the ATI graphics. Clearly there is some type of problem with this game...and it doesn't happen with other games.
I am careful to check the box for hardware requirements, and all the specs on this box were LOWER than my laptop's capabilities.
At minimum, Lucas Arts, Obsidian, or someone should allow a refund for the folks that bought this with the expectation that it would run according to box specs (mainly the laptop users).
Does anyone have an idea of who to contact for any serious consideration of this issue? I tried Lucas Arts Tech Support, and they just blew me off as an ignorant Laptop user that didn't understand how Laptops are so inferior.
