All,
I just troubleshot some of my own FPS issues and I thought I'd share my solution.
P4 2.4
1.5 GB RAM
Nvidia 6600 GT 128MB
I am running 1600x1000 16bit but I turned down many of the effects (mirrors off, LOD, trees, flags, etc). When I start the game I would get 120 fps but before I finished a lap it would be down to 40. It would stay at 40 from then on out and if I added 2 AI cars it would drop to 20.
I installed speedfan on my machine and noticed the CPU was at 82C. I took my heatsink/fan out of the machine and noticed that there was a think layer of dust between the heatsink and the fan. The thermal grease was basically rubber.
Cleaned the sink/fan/chip, put some new grease on there and now I am running 60C and constant 120 fps with one car.
I might even turn my mirrors back on!
HTH
