EDIT

Made further tests. It looks like docked EFB (or closed EFB) blocks frame generation : FPS indicated by MSFS don’t change when i open EFB in a floating windows, but Game Bar indicates that FPS is multiplicated by 2 and you feel that increase when you play.

That isn’t actually the case. When you use windows game bar to check FPS it shows the total number of frames by windows.

With that I mean that if you have 39 frames and 2 windows open like you have with the efb, it counts that as double frames because of 2 windows, so it shows a total of 39fps x 2 windows = 78frames(ish)

Oh yes, you’re right. I made the test with 3 floating windows and FPS was multiplicated by 3.

So bad. What is funny is that I really felt it was more fluid :joy:

Funny you should say that because I use 2 monitors, the second monitor has 2 TBM gauges popped out onto it and when I pop them out, it does feel smoother than without them.
