I am having a poor GUI performance with Pd under Windows 10 and an Notebook with Nvidia GTX980M graphics card.

Starting with an empty patch placing and dragging objects is very laggy.

This is the same for Pd-0.47-1, and Pd-extended 0.43.4, therefore I suspect it's a problem with Tcl/Tk?

DSP and internal message handling works fine...

Does somebody have the same problem or a fix for this?

Thanks,

Matthias
