i have also a problem with my new pc, but only in lfs!!!
i have a 3500+ 1ghz ram, 6600gt and only 10-15frames at start and 30-50 at race. but it makes no difference if i turn details on low or all on high, always the same frames.
benchmark on 3dmark2005 is 3600points and fear, doom3, battelfield 2 and so on, i can all play on HIGH DETAILS, just lfs sux very hard
((
all new drivers for gpu and motherboard....
no idea now
