Have you measured at all how performance compares between Qt 4 and Qt 5 in HiDPI mode? I assume CoreGraphics benefits from hardware acceleration and although Qt's raster engine has often been faster than the 'native' engine, I wonder if that will still be the case when processing 4x the number of pixels on a Retina-era Mac.
