KF crashes to desktop on christmas map

[jigglywiggly]

It usually crashes when the zombies just start, I am not host. Happens to my friend and I.
I have 2xgtx 460 in SLI, he has 2x4850s in Crossfire.

Usually happens when loads of zeds spawn and getitng ready to fight. Anyone else experiencing similar issues?

Oh and it happens often when you pick up new weaposn.
I just picked up the ak47 and this happened

Crashes seem to happen the most on the santa map
