It says in the SDK documentation that PowerVR can do Full Scene Anti Aliasing and supports 2x horizontal, 2x vertical and 4x anti-aliasing, however I can’t find how it’s enabled. Anyone know?  
thanks

Ok, now I see it’s done with eglChooseConfig. Unfortunately, the iPhone uses some extension to bind the surface instead of the standard egl way. I wonder if it’s possible to use egl?

I’d suggest sending a feature request for anti-aliasing to Apple.

I tried logging a bug, but for some reason Apple won’t let me log in with my id. ☹   
Oh well.&nbsp;
