Editor is laggy but the game is not

Development Getting Started & Setup

Hello there! I have this problem. The editor (Ui and the game preview window) are really laggy. But when I enter something like an actor editor it runs fine. Also if I run the game from the preview window it’s fine. IDK what is causing this? I already tried to add UE4.exe to the Nvidea 3D settings and to windows graphic settings. I turned off realtek.

My specs : HP Pavilion Gaming Laptop 15-ec0xxx
AMD ryzen 5 3550H with Radeon Vega Mobile GFX
GeForce GTX 1650
(driver v 461.72)
16GB ram
SSD 512gb
Windows 10

I also adjusted the scalability settings in the engine…

Ok, the solution? Update the UE4… I learned that “CHAOS” is not stable at all…
