Toms Hardware Germany has a couple of articles about the 2d hardware acceleration problems windows 7 has http://www.tomshardware.com/de/WDM-GDI-WDD...hte-240480.html http://www.tomshardware.com/de/wddm-2d-per...hte-240487.html Also the US version has a translation of the first part: http://www.tomshardware.com/reviews/2d-windows-gdi,2539.html They don't center their findings in GUI drawing, but on basic 2d primitives and blitting, but they come to the same conclusions as the videos in the first post. Microsoft should bring back 2D hardware acceleration. (it's a shame but I doubt they'll ever move a finger about)
