As the title says the 4.27.2 editor freeze when hovering the scalability settings button. It is exactly the same issue like this: UE4 4.27 out of memory crash on opening scalability window - YouTube, but the editor doesn’t crash because out of ram.
I watched the process in the task manager when I try to change that, the editor got suspended then did not respond.
I can’t rid of that issue for months.
I tested on another computer as well, but everything is fine on that. I even reinstalled the Win 10, Epic Games Launcher, and the engine too.
I found this problem was due to a massive shader compile getting ready. Literally locked up for about 5 mins, and then spent 45 mins compiling shaders.
I had this issue just a few minutes ago. Choosing “Scalability Low” was giving freeze.
So I did simple Blueprint in actual level on BeginPlay → Set Scalability Quality to Epic and voila. It worked. I hope it will work for you too.
Mine issue appeared after Blueprint node “Run Hardware Benchmark”. Took me two * hours to figure out what’s going on. I was one step to use Perforce and step back with some stuff
This doesn’t seem to be a permanent solution however ,restarting the editor causes the issue to return until you run the fix again, which isn’t quite a full solution.
So if I create a new project, it defaults to medium scalability (yellow button on toolbar next to show in the viewport. If I click on that, or in the settings dropdown mouse over the scalability fold-out the editor will hang and the memory will climb til full.
I’ve tried verifying files, and reinstalling but neither worked.
I tried a blueprint solution given above where on begin play set scalability to epic. This fixes it for that session, but on the next launch the editor has defaulted back to medium.
I am going to have a look through .inis for where it’s set and see if I can change it there.
check what you have in Engine/Config/BaseScalability.ini, donot change it, just check, then what has been written to project DefaultEngine.ini and if you have DefaultScalability.ini
