Usually all 2D-operations already are hardware accelerated on any card
that is newer than, say, seven or eight years. ;)

The problem is that there's too much communication going on between
the main Pd process and the GUI at times.  Matju is trying a fix with
DesireData, a temporaty solution is inside of Pd since I think 0.37
where Miller introduced throttling for some GUI objects. 

But the simple fix still isn't enough as everyone can easily see by
moving around two or three active [vu] objects. Or by playing with
lots of data structures visible. (Hidden data structures are fine,
