Not on this app. Also the tablet in question is single core processor so implementing multi-thread is actually even worse. As a detail I left out on above story, this is one of the first surface tablets running Windows 10. I mean it needs W10 because security update reasons, but it was not designed to run such a demanding OS. And then comes my app that requires even more processing power of an already filled up to the guts hardware. Hence the breaks on demanding too much processing.
