Unity 2018.3 BAD Performance

Hi,

I know many topic are already created for that, but no one fix my problem ...
"WaitForTargetFPS" ... I do everything i read on this forum but he's always here.

 

WaitForTargetFPS is either a result of VSync being enabled or the value of Application.targetFrameRate. All it means is your game is trying to hit a specific FPS but finished its work early, so it needs to wait before starting the next frame.

https://docs.unity3d.com/ScriptReference/Application-targetFrameRate.html

 

As you can see on my screen, my scene is empty, and i disable vsync on all quality
I have to force with script the frame rate to fix the waitfortraget ...

 

You seemed to have ignored half of my comment.

While your game is running, output the value of Application.targetFrameRate to the console. While you're at it, I'd output the vsync settings too in case you're running some asset which changes them at runtime.
