You probably remember, recently i have been fighting with my new NVidia GT6600 (OpenGL 2.0) and the last Linux driver (OpenGL 2.0), those are perfectly working. BUT An Exception FG, does not. I have found in FG itself a functionality about lighting animation which makes the problem. It was working with the older drivers (OpenGL 1.5). I had to patch FG, because i need a hight speed graphic card, I don't hope any come back from NVidia. The graphics card suplyer, don't take care with the old releases, they answer to the instant mass request. With FG Beware OpenGL 2.0.
