Cowie is saying the same thing i am. Last time we saw "large" performance gains from new AMD drivers they had changed the entire IQ (Image Quality) structure of the drives so they favored speed by reducing IQ with the default settings. Later on they did admit doing so (after word got spread) and not a word about that since. So once again something like that might have happened, it has nothing to do with Wizz and any other reviewer. However there are those who will sniff out any "tweaks" made by AMD that May sacrifice quality so we will have to wait and see.
