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.
Is your vectorscope refresh dominated entirely by the
rendering, or is it computationally bounded too?
If it is just the rendering time that dominates, it might
be worth trying to see if GL would draw it quicker (since the
GL path is likely to be using the 3D hardware accel. in the
GPU and hence could be "much" faster.) Well, at least on
machines with GL support in the hardware of course, though
that is pretty commonplace these days.
But it is a lot of work to port the drawing, though...
Yes, I should be drawing it with GL. It is much faster. I am now
porting the code.
