I am facing the exactly same issue guys! the FPS are so unstable in this release. In the same aiport, same conditions, same settings, same hour, etc I have sometimes 25 to 30fps or… 45-50…
I am saying this without moving the camera… maybe you press the restart button and you’ve got a fps increase… This is weird…
I have been playing a lot with the usercfg parameters and I can state I did’t find any root cause of this… even when I change everything to low the sim cannot increase the fps as well…
I did also a fresh install and still have the same issue…
Everything at default without addons…
