Hi

iR won't do RGBA with 12 bits per component and 8 multisamples, irrespective of
pixel size. You can get RGB (no alpha) 10 bits per component with 8
multisamples or RGBA12 with 4 multisamples. Note, for screen-door or blended
transparency ( pfTransparency with PFTR_MS_ALPHA or PFTR_BLEND_ALPHA ) - you
don't need source alpha so you could use RGB10 and get 8 samples. This doesn't
help you if you need the source alpha for other purposes though...

Cheers
Rob
