Re: Performance issues?
It doesen't matter as far as i know, how new your grafic card is. The game won't use all features, so it can happen that the new tech does not fit that well for the old game.
It is a advanced and improved Q3 Engine wich EF2 is using. I do not know about dual core cpu's, but it coud be possible that the game does only use one of the cores. The game is also extremly hungry on high details!
But what i can say for sure is if you pushup antialising and anistropic filtering you don't have to wonder about bad frames.
Those featrures are very hungry, and i don't know about your card, how it handles those features. So this means it can be the game as well as your hardware in comination with the features and software you are using.
If i push it up to the maximum (i have to admit my card does not have DX9 support) then i get on the best time 30 Frames and on worsest time i got 0.8 (zero point eight) and this is not a joke!
