WACOM Mobile Studio Pro

I have been having huge problems with Storyboard on Mobile Studio Pro. I have had Toon Boom Support looking into it for months (now seem to have washed their hands of it as I have heard nothing back for ages) and I have been trying to get Wacom support to help too, with even less success.

I wondered if anyone else was having problems with laggy drawing and slow loading while using the mobile studio? Or is it just my unit? No one seems to be able to explain why my 9 year old PC performs better than this brand new mobile studio which, on paper at least, should be so much more powerful.

Thanks for any help in advance!

Oh and I have noticed a decent amount of lag in Painter too. SO I guess I’m just wondering if anyone else’s mobile studio is having performance issues in general.
