When I play the game I have serious performance issues and frame rate spikes and general slowness. When I open task manager I see that javaw.exe is running over 1.2 GB in memory. When I save and quit to the main screen this memory usage remains at over a Gigabyte for several minutes. This is a clear symptom of a memory leak as the program is tying up memory that is unnecessary for what the program is doing. I have 5 screenshots with the minecraft window over the task manager showing the increasing amount of RAM that is being used by the Minecraft javaw.exe application. During this test I did not move far from where I started when I loaded the game. Please fix this game breaking bug.
