Thanks. That would be very helpful.

Ok.  I was able to test it with my viewer.  I did not notice any slowdowns except for the vectorscope which draws a lot of points (lines) in all directions.  In that case the slowdown was from 5 iterations of the vectorscope down to only 3 iterations during playback.  Also, I did not see much improvement in any of my widgets' antialias except for some round buttons.

I wonder... is there any way to draw aliased lines when gdi is on?  That is, temporarily turn it off, so that I draw all my vectorscope lines fast while the vectorscope markings are drawn antialiased.

Other than that, in my case, the pros are not enough to have it turned on by default.
