[Tip]Anti-aliasing and Filtering with Little-No Performance Hit

Driver overloaded AA may either change the settings for aa framebuffers (so msaa to ssaa or csaa switch) or enables AA for the default framebuffer.
AA in the default framebuffer isn't useful as we don't render into it (and in fact, it will break the ogl backend). Also AA config changes for the other backends can't increase the number of used samples, so every 4xMSAA setting in dolphin would results in a 4x..AA.. result.

As you don't see an slowdown on forced SSAA, I think you've only enabled SSAA for the default framebuffer. So you can be lucky, the rasterfont will look nicer
