I'd like to see screenshots which show this "higher quality".
Xmas puts his finger on the heart of the matter. But this is a gaming benchmark, so not only do we want to see static screenshots which can bee zoomed in at individual pixel level (which is much too stringent), we want to see demonstrated the relevance of this at 30 or 60 fps in actual games on actual devices. And if it is, indeed, demonstrable (hah!) then we can discuss the costs involved...
How many decimals of pi do you need to make a wedding ring? 2? 5? 47? At a certain point it is simply good enough, and you optimize for other parameters.
