Huge Performance Drop

[TOO_SWOLE]

First off, I have a Radeon 7850 2 GB GPU, 16 GB RAM....

Ran perfectly fine on Ultimate when I first installed it about 3 weeks ago. I played a few times, got busy and stopped for a couple weeks, then just installed the updates and booted it up again yesterday. Now I am only getting 20 fps on LOW settings.....WTF!!

Has anybody else had problems after the updates?

Nope, in fact quite the opposite. My performance playing on full graphics has upgraded more than 50%

AMD released a new set of Certified and Beta drivers. I'd check out the latest Certified drivers since they come with all the fixes the 13.3 Beta 3 drivers had for this game and many others.

Scroll to the bottom of the page and you can select either the 13.4 or 3.5 Beta 2 drivers.
