[Q]

1) Check to see if the game is running on a single core by alt-tabbing out of it, opening Task Manager, selecting the Processes tab and right-clicking on swkotor.exe. Select "set affinity" and see if just one or all of your CPU cores are checked. If they are all checked, set the game to run on a single core according to step 8 in post #2.

2) Make sure that 640x480 is on the list of supported resolutions in your Nvidia control panel. If it isn't (it isn't by default), add it using the customize option.
