Bill I do use Vista...and asio4all.. on my laptop...I have the same results with another laptop running XP and asio4all..(this is an older Compaq and not as powerful as my Toshiba running Vista)..

They are not performing badly...but noticeble while I play and feel the connection to the key response....just enough to annoy me, especially when I play the MS with better results...I always thought it to be a Windows problem...MS runs Linux..
