Feedback Macro

I've been getting pre-occupied with supersampling and how , when fed into a Feedback macro, it won't faithfully render in full screen, what it will render within a viewer window.

Have tried all sorts of tweaks, but thus far, whilst plain supersampling results in good performance at full screen, one sent through a feedback loop basically fouls up .

Any workarounds ?

BTW - a lot of this has been whilst looking into some of the nicest OpenCL and GLSL QC examples I've seen for a good long time from http://t-linked.com - thanks to Steve Elbows for posting that link to some impeccable GLSL and thought provoking ways of making OpenCL render to the Billboard with supersampling.

See here for the sort of results that you get when rendered faithfully to the Viewer window.
