When I undock (pop up) at least one instrument panel (press right ALT key and hover your mouse over one of instrument panel until the mouse sign change to a plus sign and click to undock it), I notice my FPS change almost double, from around 30 FPS to 55-60 FPS. I would have thought that by undocking or popping up instrument panels, FPS will drop since the GPU has to drive another pop up window. But instead, the FPS increases. Anyone experience this? It’s a nice surprise for me but what cause this? Or I am missing something? I am using MSI Afterburner to show FPS.
