The same hardware and the same settings I had before installing the last patch, running LFS with no problems :icon23:: AMD Sempron 3000+, 1 GB ram, GeForce 6600, 1280x1024, 2x aa, etc.
I'm experiencing some FPS problems in LFS. I used to drive at 100 FPS in every single car/track combination until I installed the last official LFS patch. Since then, i'm getting random FPS drops for 1-2 seconds, going down to 0 and then it comes back again to the 100.
Look at the following graph. It shows the FPS evolution in a 5 laps test in LFS:
No other processes running, graphic drivers updated, etc... What else should I look for?
