This is way off-topic, but TSR stood for "Tactical Studies Rules." The company started with tabletop miniatures wargame rules. Dungeons & Dragons came later. Advanced Dungeons & Dragons came still later.
On-topic, more or less: The NVidia drivers starting about that time also began reporting a bad variable of some kind to DirectX. I had to download a patched version of System Shock 2 to get around that bug.
