> he way it's working in my mind has about the same number of lookups as FXAA, However, the FXAA will have a clear win as it works over a partly transparent polygon. So you will have to combine both an RBG and z based to get the same result as an FXAA. > you're dependent on bandwidth between the GPU and its memory, not main memory. The bandwidth I was talking about was the older cards which do not have bandwidth or fill rate to keep 60fps with deferred shading, no AA. FXAA would be a candidate there if it is a pure RGB technique on the composited frame, especially as it is cheaper than MSAA.
