Pop out window to secondary screen decreases fps from 60 to 20

Do anyone have a solution for this? I’ve tried a lot of gfx settings both ingame and with nvidia tool, but as soon as I move for example the VFR map or some instrument to a separate window (so I can put it on second monitor) the FPS goes from 60 → 20

As you can see I have quite good FPS otherwise, even in san fran I have 50 fps.
1080 TI
i9 9900K

What I’ve tried:
Vsync on/off. Set/remove framerate limit in nvidia tool. Different mysterious settings like “performance” etc in nvidia tool.

Seeing everyone with multi monitor setups there must be some way to fix this (?).
