I recently updated to Mindcrack 8.01. On doing this the game takes a very long time to launch and when I finally get in game my fps won't reach over 6 and chunks load at a very slow rate. Before this update my computer ran it smooth as butter. Here is a pastebin of me doing a fresh install, most of this stuff comes up even if it was already installed which seems to make it take a while to load.
