I assure you, it does not work on modern hardware, at least not correctly. It has issues with high core count CPUs, high refresh rate displays, uses several proprietary obsolete opengl extensions that are not supported by modern drivers, has several stability issues especially around cutscenes and area transitions, and the list of problems goes on. It kinda runs if you're willing to disable half of its graphical settings and are willing to deal with the frequent crashes. The KOTOR community, including myself, have been vibe-coding patches to keep it alive but it's not ideal.
