Big Amount of Chunk Updates Lag

Hi there, my name is Cr4xy.

I have a big problem with my Minecraft.
My Specs:
Intel Core i7
NVIDIA GeForce GTX 760M
----------------------------------
After the update 1.7 i have very much chunk updates. (100-800).
When i stay at the same point 2-3 minutes, its getting to 0.
But short after i move agian it gets high agian.

(I have 60-300FPS, but the chunk updates cause a annoying lag and destroy the whole fun.)

PLEASE, MOJANG, FIX IT!
