After some experimenting and thinking why LFS runs to me slower than it should I've discovered following.
When I was using official drivers for my integrated CMI9880 audio, in LFS Benchmark I got about 10-15 FPS lower results than now. Problem disapperared when I've installed UAA HD Audio driver(supplied with WinXP SP2 - thats how it seems to me). The whole secret why are these drivers faster(I can get over 100 fps when alone, before 50-60) is because they DOES NOT support EAX. I did tests with SBLive! 5.1 and got same performance drop!(to be exact, with SBLive! it was a lite faster)
--> EAX effects SLOWS LFS ON CERTAIN SYSTEMS.
EAX are in use when LFS is running, I can hear reverbed(and silly sounding) sound.
