Yeah... well, I'm not sure adding it was such a leap forward; nearly all of the performance bugs have the word 'slow' or 'performance' in them. But time will tell. I created the page http://wiki.winehq.org/Performance as well; it has handy canned queries that pull up the bugs you found, plus a few others. > My personal objective is to getting Devil May Cry 4 Benchmark above "D" rating Please consider adding support for that benchmark to yagmark ( http://wiki.winehq.org/yagmark ).
