comment How can I make a 32-bit render target with a 16-bit alpha channel in Direct3D?
I'm also looking at getting this working on another target platform, and it turns out it doesn't support G16R16F, so I'm hoping to find a way to encode 2 8bit channels into a 16 bit channel and still support the blend modes for downsampled translucency

That's a good suggestion, worth looking into. What about encoding a float into 2 channels? Like, putting luminance in RG and alpha in BA in a R8G8B8A8 render target. Are there good examples of this anywhere?

It could be that there are better ways of doing that implementation. It did help us out in the worst case, but hurt us in the average case, and ultimately wasn't a big enough win to justify putting it it. I have heard of hardware specific tricks that require only one pass, taking advantage of MSAA to render downsampled translucency while using a full res depth buffer. But I haven't found any info about that online, it may be NDA information.
