All drivers after 12.8 beta, till 12.11 beta7, World of warcraft, MOP x64 Client run at a maximun 15-18 fps when AA & CrossFireX is enabled on the 5870M (5770) CrossFireX Mode, much slower than a single 5870M at any driver.

In addition, the app profile only worked on 12.8 cap3 forced Wow.exe on Wow-64.exe. All cap after that with original wow-64.exe will show the same low performance, lower than a single card.

The water flickered and waves slowly when AA & CrossFireX are enabled after 12.8 and 12.8 Cap3

Alienware M17x R2

AMD Mobility Radeon HD 5870 CrossFireX

Windows 7 x64 Ultimate Intel Core i7-820QM

Power Supply 240W (Adaptor should be Okay cuz it runs smoothly with Catalyst 12.8 beta + 12.8 Cap3 forcing Wow-64.exe with Wow.exe profile)


The Problem now is any driver after 12.8 beta will result in the performace in CrossFireX lower than a single card when AA and CrossFireX are enabled, no matter 12.9, 12.11 beta 1-7, App Profile 12.9 Cap, 12.10 Cap1 original with Wow-64.exe profile. Also the water in WOW waves stumblingly and pausing at intervals, when CrossFireX and AA enabled.
