Actually we're bugging the test with running it with Vista/7 as there was no Aero when pcmark05 was developed and than we trick it again by running Internet Explorer 7,8,9. In both cases calculation gets done which was not intended by the devs. While this maybe excused by the technical advance during the years, allowing registry tweaks cant be the way to go. It simply leads to no rendering in transp windows and IE of rendering blank white pages as the same like video compression calcs something that is less demanding than audio compression.
Dont get it, why dont we just drop this bench? Only thing we do here is restrict "super tweaks" but we're still not run the bench like it was intended. And I fear this isnt even possible today.
