Editor fps drop drastically using editor in a ultrawide monitor (3440x1440)

I am using two monitors, AW3418DW (Ultrawide, 1440p, gsync) and another one that is just normal (1080, 60hz, etc.).

In the classic monitor (1080x1920), Unreal editor works perfect, smooth.
In the ultrawide, Unreal editor fps down extremly. And it bothers a lot.

Someone knows why is happening this? Any other window works fine in the ultrawide monitor, but Unreal lags there. No matter if it is maximized or in a small window, it goes laggy. If I put the editor in the second monitor, it goes perfect.

CPU & GPU, RAM, etc. are not at 100% (20% CPU, 45% GPU, 40% RAM)

Intel I7 7700K, 16GB RAM DDR4 3000, Nvidia RTX 2080

Mouse focus in one editor window in the old monitor: 120fps
Mouse focus in one editor window in the ultrawide monitor: 20-40fps

It should not drop, this setup should work fin in both resolutions. Does it only drop in editor? What about unreal games like Fortnite is same resolutions. Or not unreal games.

Unreal games (Sea of Thieves and Ark) and other games (The Division 2 beta) run perfect.

The editor is not compatible with g-sync, you have to turn it off for it in the nvidia control panel

THAT’S IT!
THANK YOU!!!

I configured Nvidia to disable gsync just in the editor.
