Never be afraid to ask, but don't demand an answer 
I gave the editor a go a few weeks back and it's just too slow for me to use. Every time I move the mouse the CPU usage spikes tremendously. I am guessing there's no hardware acceleration, is there?

Oh, that's bad. There is no hardware acceleration, indeed. I did however add a setting for making it faster at the cost of appeal. If you disable the backing store, it should flicker when you do things, but it should do the things a lot faster. To try it, change the value of "nobackingstore" in pde.gui from "False" to "True", using a text editor.

But it shouldn't be slow to just move the mouse. Dragging with a button pressed might, though.

On the other hand, it was slow but acceptable on my old laptop, which had very low specs. Now I'm using it on a 2.66GHz machine, and it is really fast, even when zooming out and having a lot of things at once on screen.

I have seen some other programs which become really slow when running them on Windows; perhaps Python isn't optimized for it. If that is the problem, there isn't really anything I can do.
