I've noticed that when playing windowed games on my Radeon 9800 Pro, windows tooltips will slow them down to a crawl while AA and/or AF are on. While a tooltip from any program or the system is onscreen, games will slow down so far so that you can literally see frames being painted to screen. This happens whether or not the tooltip is overlapping the game window. I've knocked down one similar culprit of system-related slowdowns: menu shadows, but any tooltips still cause the problem. Curiously enough, menus without shadows cause no slowing at all. I've googled the problem and searched several forums with nothing to show for it, so if anyone has insight to how to solve this, I'd appreciate it greatly. Sometimes I simply cant play games fullscreen and lets face it - playing games without AA or AF isn't an option anymore, so being rid of this annoyance would be of great help. Currently using 4.2 Cats, slowdown happens on multiple systems with the 9800 Pro and 9700.
