Low Chunk Updates = Low FPS?

[Arrow]

This is getting really annoying, and it doesn't even make sense.
I've tried allocating more and less RAM and it makes no difference, texture pack or not makes no difference, not even render distance helps.
The only thing I've found out is that it's to do with the Game Render, it's up to around 75%.

Oh and I just caught it at 3FPS on 0 Chunk updates... -.-

What is your system specs? Is this a new world?

It's a relatively new world, but it happens on new worlds anyway.

My specs are:

Intel i5-3210M CPU 2.50 GHz
6.00 GB RAM
Intel HD Graphics 4000
NVIDIA GeForce GT 650M

So this really shouldn't be a problem. :/

Hm, I have solved this after trying many things. I allocated extra RAM to my Java too. All is fine now and everything is stable. Thanks for the help

I just wanted to check that you are using the nvidia card and not the Intel one.
