AFAIK all pre-vista OS's have issues rendering to a second monitor in dual view. Vista is a little better but still not nearly good enough for me. The only thing I find acceptable is xp with horizontal span (you cannot do span in vista, evar).

With the same hardware, 2 instances of <any directx app> running under dual view monitors, I got max ~5fps in xp and ~20fps in vista on the second monitor.

Same hardware under xp with horizontal span - with FIVE instances running, I can get 60 fps on any window.

Is there any way to avoid having system pop-ups appear in the middle of the setup so the dialogue boxes get cut in half? Because I find that highly annoying. Running vista atm and tbh I'm a bit tired of the poor performance.
I searched high and low for registry settings to change this is xp span mode. I didn't find anything.
