Put the summary of the bug you're having here

What I expected to happen was...:
I have a high end desktop and I usually run my render distance on far. Before 1.6.2 I had no issue, I could see far perfectly.

What actually happened was...:
Whole chunks of the world don't load until I'm almost past them in flight. I'm talking gigantic chunks. I just see open sky. I've updated Java, and my graphics card to no avail.

Steps to Reproduce:
1. Set Render distance to Far
2. Attempt to see things far away
3. Fail
