Recently I changed my nVidia GeForce FX5700 for an ATi 9600PRO. Downloaded Catalyst 9.11 (latest for that video card) and started the problems with LFS.
I can play any game I want (like GTR2, GTL and others) and someteimes the framerate slows down a bit but I can play for as long as I want.
When I play LFS sometimes the framerate goes down to 20-30fps, normally I play with 90fps, and sometimes the game stops responding. The Catalyst signs an alarm and closes LFS.
I'm going crazy and already miss 2 races because of this problem. I'm thinking about getting a new GeForce 7300GT, but I have to do something with this ATi.
