I haven’t played the Sim since Dec. Recently I upgraded my CPU (9700K>5800x) and my motherboard, as well as increased RAM (32GB>64GB). I play on a 4K main display with two small 1080p monitors for Avionics and ATC displays. I’m starting with a new install of Windows and the Sim (re-installed from scratch yesterday with the hot fix version). I briefly tried the latest Nvidia drivers but started getting CTDs during brief testing and rolled back to 457.51 drivers from December which seem stable.
I’ve found two things that DO NOT match behaviour from Dec. related to undocking Windows.
First, is that undocking windows has a dramatic effect on FPS. For example, the mere prospect of undocking the ATC window results in about a 20FPS reduction…
Frame rate with no window undocked…

Second, When Vsync is on (60Hz) the frame rate is limited to 30FPS once you undock a window. With no windows undocked, the FPS will remain around 57FPS with vsync on or off.

Third, Possibly related to these issues, is that back in December, undocking a Window with Afterburner OSD on, would result in the undocked window also getting an overlay, and the reported FPS being doubled. This is no longer happening.
Can anyone else confirm these observations?
Similarly, I’d love to hear from anyone that doesn’t suffer a FPS penalty from undocking a window, as I’m almost certain I DIDN’T suffer a FPS loss back in December. I’d like to know if it’s possibly something in my setup or something recent in the sim.
