I can confirm this. As soon as HPF or/and LPF is engaged, moving the nodes is like trying to stir dried concrete. Even to make very small adjustments, I would need to drag the mouse over half of my desk. I just tried all the different EQ resolutions...no difference . To me this is a not fully functional feature of X2.
And yes John, #1 to an optional large display! This has been requested here for so many times, and would make eqing-life in PC so much easier
