According to AMD/ATI the new Catalyst 10.9a Hotfix drivers address some issues with the HD4850x2 and HD4870x2 video card performance. Hopefully this is the case, and hopefully it will address an issue that has been seen around the web dealing with CrossfireX on some of the HD48xx's and even some HD5xxx series of cards running specific motherboards. This issue is not really wide spread, however there are some of the "gamer" series of motherboards that have experienced this issue, and we can only hope that AMD/ATI has addressed these issues in the new "hotfix" drivers. This issue was addressed in the Catalyst 10.8b drivers, and we have to wonder why this was not carried over to the original Catalyst 10.9 drivers.

At any rate, this is what AMD/ATI has to say about the new 10.9a Hotfix Catalyst drivers:

* ATI Radeon™ HD 4870 X2 and ATI Radeon HD 4850 X2 series of products use both Graphics Processing Units (GPU) for high performance
* Intermittent hangs with Pop Cap games in a system with an ATI Radeon series graphics card installed
* High-Definition Multimedia Interface (HDMI) overscan / underscan settings are restored upon system reboot

Download and install the ATI Catalyst hotfix from the following location:
