Hmm, that's strange. Like you said, the GPU programming guide says that D3DFMT_G16R16 is not renderable, but the caps viewer on my machine says it is. Anyone actually tried this out on a geforce 6/7?

Sigh, I hate the caps stuff ...

I believe it can have the "usage" of rendertarget (ie D3DUSAGE_RENDERTARGET), but its not a RenderTarget "format". In the Caps viewer for this laptop (Nvidia 6800 Go), D3DFMT_G16R16 is not listed under "Render Target Formats" but is listed as a texture format that can have RenderTarget usage. I believe all this means is that it can be used as a source or dest when doing a StretchRect from texture to texture. I could definitely be wrong about this, so you may want to ask Nvidia. My hunch is to believe the table in the GPU Programming Guide though.
