HDG knob - extreme frame impact in 2D panel (PMDG 737 NGX)

[koli 0]

Hi,

when I turn the "Heading Knob" (HDG not armed on my 2D panel, PMDG 737 NGX, P3D v4) I have a impact of the framerates from more than 50% and extreme stutter!!!!
When I finish the turn is again everything fine and smooth!
It would work all perfectly, only with this problem it is impossible to fly ...

This is my cockpit with 3 monitor surround view

Best regards,
Klaus
