I have a pentium 4 3,06 GHZ and 2GB Ram also an leadtech nvidia 7600GSHDT AGP game runs shit on high, also on medium but better! I now uses ATI TOOL
for ovelocking the card, not much but a litle bit! And it works, games runs stabil now! Google for the tool it is for ATI and nvidia cards but use at own risk!!! Thts not the perfect solutin its a shit programmed game from konami. a 7600GS256Mb is a fine card i can play Bioshock without probs , and a footigame ruins the frames???
Yesterday i have checkout 3 Cards also an 7950GT, the new ati 2600(256Mb Dx10 and shader4.0), and the 7600GT, same shit, also uses a framedetector and i see that in the boxes allways the frame goas down to 45FPS with the 7950GT(thats uneblivable by an 512Mb card)!
so i use the ATI Tool!
