Hello
There was a problem: in UE4.24, the FPS began to fall sharply every few seconds. This is like a short jerk or freesing as it happens in literally a second or less. This problem has spread to the entire editor, regardless of the project. In older versions (UE 4.19) there is no such problem. (In UE4.25 the same problem) Help please this problem drives me crazy.
Do you get it in a new level?
EDIT: Are you still using the default Game mode / player?
It happens
not only in the game / editing but also in BluePrints and does not depend on the playback mode.
I did what you said. It didn’t help + the scene was not what it was before.
Does it happen in other apps?
How about quitting the editor, binning config files and re-starting?
This is not in other applications.
I did not quite understand about: “How about quitting the editor, binning config files and re-starting?”
So, quit UE.
Remove all the files in
( keep a copy elsewhere just in case ), and then restart UE.
Ok, just put the config files back of course then.
Sorry, I’m just about out of ideas here… :-/
Have an idea how to transfer BP files from 24 to 19 ??
Right click and ‘migrate…’
everything except BP has passed; the folder in which it is not displayed in the editor
You can’t be editing the BP while you’re trying to migrate it…
I completed the migration. Then he went out and went into the project.
There is a folder, but there is no file in it. In Windows Explorer, it is available.
Then you are migrating to a lower version of the engine, right?
Not possible I’m afraid…
I solved this problem before installing new drivers from Nvidia
cool… 
Same problem. Have you solved the problem? I use UE5.1.1, it drops every 2 seconds in the stat unit → Game. Seems it’s CPU’s problem not GPU’s. but OK in UE5.0 or any other version.
Has anyone found the solution? UE 4.27, same thing even in empty projects.
