Continuous freezing in the Engine

Development Platform & Builds

​ Ever since I upgraded to UE 4.24, I have been experiencing a half-second freeze every three seconds. During each freeze, 2 cores of my 4-core CPU are used. No logs are printed during a freeze. The freezes occur in every part of the Editor, PIE, and even in packaged projects. I have tried building the derived data cache:

./Engine/Binaries/Linux/UE4Editor MYPROJECT.uproject -run=DerivedDataCache -fill

but this doesn’t help. This issue happens even in a blank project with default configuration. My OS is Arch Linux, and my graphics card is a NVidia GeForce GTX 750 Ti with 1 GiB of GPU memory.

Do you have the same issue when you use OpenGLDrv? Pass -opengl4 flag when you start the editor and see if that help. If yes, then there is an issue with the Vulkan Driver/Implementation etc.
Also make sure when you use -opengl4 that you have:

+TargetedRHIs=GLSL_430

Added to your [/Script/LinuxTargetPlatform.LinuxTargetSettings] inside the BaseEngine.ini

Since the upgrade to UE 4.24.2, I have no longer been experiencing this issue.

The problem was exactly like this, so maybe this can help if you have this problem, even though I don’t have it anymore:
