Full scene anti-aliasing is disabled when using AMD Fusion GL device, this APU actually supports 8x multisample, it can run other multisample enabled application, so why Solidworks disable this option? With the same platform, if i using a discrete AMD Cayman GL, this Full scene anti-aliasing option is enabled so it's so weird.

With online docs: http://help.solidworks.com/2011/English/SolidWorks/sldworks/LegacyHelp/Sldworks/Display/HIDD_OPTIONS_EDGES.htm#

it says that:

"Full scene anti-aliasing. Available if your video card supports full scene anti-aliasing and has passed a stability test. You must set the graphics card control panel settings for anti-aliasing so that the application has control. Applies anti-aliasing to the entire graphics area for parts and assemblies. Anti-aliasing is disabled during zoom, pan, and rotate. "

So the video card should pass a stability test, what are these test exactly?
