I currently have the AMD Radeon HD 7770 with the Catalyst version of 13.12.. I went to the website and seen that the Catalyst Version 14.1 Beta has came out and does support the Radeon HD 7000 series. Should I upgrade to the beta? I've been having troubles in COD:BO2 (drivers crashing [Yes I have enough Wattage]) and Battlefield 3 (DirectX error saying stuff like my device is hung, it has giving my device bad commands and things saying "GetRidDeviceReason")
14.1 has been presenting problems with some cards and systems. Running fine on others. I tried it on my FX-8350/HD 7870/Gigabyte 990FXA-UD3 system, and it caused BSOD. So try 14.1 at your own risk.
You may have other issues. Try running CCleaner and do the Clean and Registry portions both to rid the system of registry errors, junk files, and resource wasting crap. http://www.piriform.com/ccleaner
I just went back to 13.12 from 14.1 on my system. Crysis 3 wouldn't load in to the level, and EVE was crashing on loading as well. But, it's a beta driver, so it is what it is.
You don't really stand to benefit from it anyway, as that card isn't supported for mantle with 14.1. Support for you will come later, so I would just stay with 13.12 until a new, non-beta driver is released.
