    Full scene anti-aliasing is disabled when using AMD Fusion GL device, this APU actually supports 8x multisample, can run other multisample enabled application, so why Solidworks disable this option?

      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?

          If you enable anti-aliasing in your graphics driver, it will work whenever the part is being rotated, whether you have a supported card or not.  As soon as you release the middle-mouse button or take your hand off your 3D mouse, your edges will appear aliased unless FSAA is enabled in Solidworks.  If FSAA is enabled in Solidworks without anti-aliasing being applied in your graphics drivers, edges will appear aliased during rotation.  It should be noted that the built-in FSAA display option is only changeable when no files are open in Solidworks.

           

          When they say "pass a stability test" what they mean is your card should be a Quadro or FirePro.  Basically, Solidworks disables FSAA and Realview when running on any other card.  Why?  They must be getting money from AMD and Nvidia to help drive sales of expensive "pro-level" GPUs.

           

          If a pro-level card is out of your budget, I have heard of a hack which enables FSAA and realview on any video card.  I don't know how kindly folks around here take to discussion of such things, though.  You should probably look around somewhere like www.reddit.com/r/solidworks for more information.
