π΄ UEFN / Unreal RAM tip
If youβre running into RAM issues with UEFN / Unreal Engine, this might help a lot.
I cleared my Derived Data Cache folder and removed over 140,000 files, which immediately improved performance and significantly reduced memory usage (in my case).
π Path:
C:\Users\YourUser\AppData\Local\UnrealEngine\Common\DerivedDataCache
π’ Unreal will rebuild it when needed, since this folder stores compiled shaders, textures, and other processed assets.
β οΈ Over time, especially across multiple projects and engine versions, it can accumulate a lot of unused data.
β‘ Not a universal fix, but in my case it made a huge difference in stability and memory usage.
