Hi. I am running minecraft on a Windows 7 64 bit computer with 64 bit java with 4 Gigabytes of ram (I allocated it with 2 Gigabytes). I am only getting about 15 - 25 fps with the best video settings i had. (Render Distance = 2, Particles = Minimal, Max Framerate = Unlimited, Clouds = Off, etc.) I really need to make minecraft faster so I can play Hunger Games without it lagging. Hope someone can help.
