Anyone try KOTOR 2?

I've been trying to get it working.

It starts off running fine and seems like it'll be a good experience, but the video keeps freezing a shortly after 3D gameplay starts (doesn't happen in the menus) - it seems despite the video freezing, the game is still running in the background (audio still plays and takes input from my controls).

I don't think it's anything to do with temperatures, as they don't seem to get very high with before the video crash (it gets way hotter with other games that have worked fine). I'm running the latest non-beta Intel GPU drivers and all in-game graphics settings are disabled/lowest.
