Are you actually trying to display content that has this kind of
resolution?

Yeah, we all are.  *Something* happened from 0.18->0.19 to cause it's
performance to tank.

If all you are trying to display is SDTV (720x480 in NTSC-land) why even
that much?

Unless you have an ancient video card, I'd be surprised that the CPU is
being asked to do this rescaling.

But all of this aside, I have to ask, if the content you are trying to
display is only (say), 720( or rather 640[1])x480 why set your display
to more than 640x480?

If what you are seeing really is the cause of scaling in the CPU, why
scale?  Set the resolution of your output device (i.e. X) to that of the
content and be happy -- don't scale.

b.

[1] there is some relationship between 720 and 640 where they end up
being the same thing that I don't quite recall
