HI all, i have downloaded and installed tekkit launcher and minecraft separately. When i try to run either i can run the game and create a new world (or load an existing one) but after less than a minute the framerate drops to the point where the game is effectively frozen. the menue take several seconds to come up and often just crashes out.
I am running the latest version of java on a 3.6GHz, 32GB ram, 680m 4GB gfx win 7 setup.
