Your so-called "Render Engine Update" is trash!!!

Every time I play this stupid game, it starts lagging within 30-45 minutes of being in the same general vicinity, and going back and forth between the same group of chunks, and if I try to go somewhere else, it refuses to render any new chunks after loading, oh, I'd say about 100 individual chunks, only one time each, and if they render more than once, then they load as two separate chunks without ever unloading.  They stop rendering, but they aren't unloaded, so thus when I move about 10 chunks with 12 chunk render distance the game has 120 chunks actually loaded, taking up memory, but not rendered.  So, FIX THIS DARN THING ALREADY!!!!
