Hi Gav, yeah that's a pretty significant performance difference from your laptop to your PC (maybe particularly with that Intel video) so yeah that could probably be why you see such a difference between them.

But I do think that I have a good shot at improving the OSX one with some minimal tweaks so I will definitely give it a try at least. I can't guarantee that it's going to cook along at the same rate as your PC but maybe if it can cure the extra stacked up movement it would make it work a lot better, we'll see.
