Title: Tekkit crashes when approaching some machines.

Version: 3.1.2

OS: Windows 7

Java Version: Java 7 Version 5

Description of Problem:

On tekkit servers when ever I come close to houses it seems that my Graphics Card crashes. I have researched this and have found that it may be because of a rotary macerator and that it might be because of my Graphics Card drivers.

I used to have this problem too, I fixed it by turning off crossfire (I'm using two radeon hd 6850), and most people I see with this issue are using ati/amd cards. Let me know if you are, and if you are running crossfire I'd like to know.

PS. I've tried different drivers, different java version, etc so don't bother, the only way I've been able to fix it is disabling crossfire.
