Hi, I have gtx260 and I need some informations. 1.If I enable PhysX (GeForce PhysX in properties) I will get better effects but I will lose some framerate (fps) in games? Or PhysX works so that you get more performance and more framerate? In 3dmark Vantage I get around 1000 more points when PhysX is enabled so I am confused how it works. 2.Is gtx260 strong enought to leave PhysX always on in games like Crysis,Assassin's creed....?
