Huge performance difference between running in new window vs Launch Mode (Packed)

this problem is happening to any project and any plataform, and I tried to disable the realtime, but the “launch Mode” still has a very low fps in comparision with the editor one (New Window or Standalone), also, in the editor it runs smoothly, but in the Launch Mode it is stuttring a little…
The problem is when I Launch the Game, so it also happens when I pack it
How can I fix that?
Thanks

Hello FilipeTessaro,

Playing in Standalone and Launching are their own separate entities. Playing in a new window is a copy of your viewport in a new window.

What you are seeing is expected behavior because of the inherited project settings in Standalone and in launch. The way to fix this is navigate to your Project Settings > General Settings > Framerate. By default the Smooth Frame Rate should be enabled. If you want higher performance and raw data as opposed to the compression of frame rates then un check the Smooth Frame Rate option. You will now notice that playing in Stand Alone or Launching will yield 2x as many FPS. You may also manually set your frame rate by checking the Fixed Frame Rate and entering a value there.

Hello!
It didn´t change anything, but it is ok, I think I know now what is going on.

When playing in standalone or launch it changes the scalability settings to high or epic decreasing a lot the fps

thanks
