first of all, thx very much for replying

1. as far as my knowledge goes, i think i did install the drivers correctly.
the ones that came with the card had an installwizard, the older of the 2 nvidia drivers that were available for my card overwrote the ones i tried
before so, i'm not sure but it felt good :]
2.tweaked alot with graphic settings and calibrating, sometimes it
freezes(screen and sound) while calibrating.
3. the prob occurs under directx 7 and 8.0a
4.in software, it just works fine(except for picture quality then...
5.as i discribed in point one.
6.this is the only game i own. in fact, i bought a pc so i could play gp3:]
could it be the pc is too slow for this game?
