The slowdown of glPolygonMode on the 3dfx is a known problem, and in the bug database. I don't know when it'll be fixed. There shouldn't be a really significant slowdown from enabling GL_NORMALIZE. -Brian |

Thank you for your answers! I was discovered a cause of my problem. It was a filtration mode (GL_NEAREST and GL_LINEAR). I have a following results of experiments with my program: Mesa-3.0, GL_NEAREST: 8..9 FPS Mesa-3.0, GL_LINEAR: 7 FPS Mesa-3.1, GL_NEAREST: 6 FPS Mesa-3.1, GL_LINEAR: 3 FPS The libraries was builded "as is" (without any additional options). I don't understand why GL_LINEAR working so slow on 3.1. |
