Hi Fiddler,

I already had Dave check this on his machine so I know it's not his issue, but I'd check out your power settings in Win10, there's a setting that seems to be the default now on a lot of machines, which slows down the processor to save electricity. It made my new machine almost unusable for music production until I found it.

This article explains where to look:

This has been the culprit for a lot of customers' performance issues lately, so worth checking out if you haven't.

Thanks
