This is the driver you want for Battlefield 4
We know that installing beta software can be scary. You never know what kinds of bugs might pop up or if stability will be an issue. At the same time, if you're wielding dual AMD graphics cards in a CrossFire configuration and play Battlefield 4, it's probably worth taking the risk on AMD's Catalyst 13.11 beta driver for Windows. This is the 7th beta release for this driver family, so any early bugs should have already been rooted out.
The sole benefit of installing Catalyst 13.11 beta 7 versus beta 6 is that it increases CrossFire scaling up to an additional 20 percent for BF4. That's a significant bump, and it's yours for the taking if you don't mind chancing beta software.
This latest release also incorporates all the performance boosts from previous beta releases, including:
In addition, these beta releases add support for AMD's recently announced Radeon R9 290 and 290X graphics cards, add automatic AMD Eyefinity configuration, and automatic plug-and-play configuration of supported Ultra HD/4K tiled displays.
