I downloaded the new ATI drivers 10.7a which were supposed to enable AA for SC2. But no matter what I do I cant seem to be able to force it , I have a 5870.
What I do is I uncheck the "app controlled" option and set it to whatever.
Any idea what I have to do or how to force it please? Tried ATI Tool as well but nothing..
Should work just to force AA to any available mode, all "filters" like tent and edge detect should work as well.
You'll notice it working if you monitor framerate, actual effect is very subtle but forcing AA has a 40 - 60% performance hit for this title at the moment.
(Similar for NVIDIA as they AA the whole image, SSAA that ATI 5000 series can do should also work if nothing else does but at a even larger performance hit.)
What are you monitoring it form anyhow, cutscenes and such won't work and only the actual game is affected.
Catalyst AI controls all game specific extra optimizations (And enables CF under x2 or similar dual-card configurations outside of using the connector.) so yes it would be needed for this functionality to work.
Easiest just to keep it at standard, if some game causes problems try by disabling it, advanced tries to enable further optimizations which can cause a light drop in overall image quality or "sharpness" and also attempts to override Crossfire to work under the alternate-frame-rendering or AFR mode although actual performance gains or image differences when comparing are minimal at best.
(Might be some difference but usually it's unnoticeable in nearly any game, application or situation tested under.)
Low-level driver specific tweaks for a game to actually function and render properly is kept out of Catalyst AI however and it wouldn't surprise me if some optimizations still applied as well even with the AI option disabled.
(Roughly speaking it allows extras like AA under UE3 titles and forcing AA/AF under other titles a bit better while adding some light optimizations specific to each games profile, thus the latest Rage3D or 10.7 ATI XMP profile pack is recommended as well though lately it's been rather few changes to it.)
EDIT: Forgot the link to it, also bundled monthly with each driver revision but hosted here as well and often updated in-between driver releases though again it's rather minor most of the time but it helps. http://www.rage3d.com/xmp/
Signature/Avatar nuking: none (can be changed in your profile)
