I don't know. Give it a try and let us know.

The Universal Widescreen Patcher didn't work for me for some reason (it did in KOTOR 1, but not KOTOR 2), so I found this one. Works like a charm. 1920x1080 looks great. Also important (if playing at this resolution) is the 16:9 minimap fix

No problems here. Anisotropic filtering at 16x Game Resolution at 1920x1080 Radeon 4870 Cat 10.7 drivers
