Hi mbucchia,
it seems i was a bit too fast yesterday with my results. I tried again today with direct comparison with and without your tool. And i can see no difference in sharpness. That was perhaps because of the difference with motion repro on/off.
So it still could be a slight increase in performance, but not much i think.
Perhaps this should be implemented in a deeper layer, like in wmr (where we can switch between 60/90 Hz).
But thanks a lot for your effort!
