Very nice! My VR project relies on SSAO, so I’ll have to wait until that is supported, but 22% performance improvement definitely sounds very nice 
At the moment I can let SSAO run on lowest quality setting, without AA there are many ugly patterns visible, but Temporal AA is blurring the AO so that it looks very nice. Once SSAO will be supported in the forward renderer, could you maybe directly implement the blur shown here: Screenspace blur for SSAO [C++] - Rendering - Unreal Engine Forums to the forward renderer, since the usual TAA blur will not be available? With that blur it should look great on lowest quality with MSAA.
