I dont know what it is, all i know is that I cant play on the highest setting of this gameand i have a great system. I try to save the settings of the game to high res, ultra quality graphics and 16x antialiasing and then save. Nothing happens. It doesnt take affect. I tried every other setting underneath, but all that the game plays on is 1024 x 760 or whatever that res is. Even if it isnt my moniter and its my system, why cant this system handle it, and what can i do to fix it, even if it means i have to buy another piece of hardware. Please help me out..... I think its my moniter but maybe i need an update for my video card. Thanks

Why do you have a 15" monitor with that system. You're crippling your experience.

You should be greatful to be able to run in high...mine can't even run low smoothly...hehe

Thats the point...there are no 512MB Gaming cards available right now. IIRC, there are some workstation and professional cards that carry that much RAM, but they aren't built for games.

Ah, but are we talking Double Density or High Density?
