Hello, since I started using LFS (2004) use the same PC, and new versions of LFS were lowering FPS.

In a race with more cars this at 15fps, with no other cars on the track I have more than 30fps.

I want to improve the FPS a bit, just a little, I can now buy a new PC.
Adding memory I will improve something? 1 GB more.
Or directly a new video card?

Both things I can not.

Some settings do you recommend?

My PC:
Atlon XP 2.3
Mother ASUS A7V8X-X
512 RAM
Gforce FX5600 128 MB

Already thank you very much
Julian
