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.

I think that possibly the PC driver has some kind of throttling / message coalescing built into it that the OSX driver doesn't do. But luckily that's not too complicated to implement. (yes, famous last words... ha)

:-) That's cool if you can.
It's not that I expect it to fly, but it's the stacked up movements after I've stopped that's the killer. I over compensate back the other way and .... you get the picture.. It's like wrestling an eel :-)

Btw, I just noticed the time of your response, given what I assume is about 5 hours difference min - you need to sleep :-)
