Summary
In UE 5.8, blueprint search performance got to the point where it’s barely usable. It is extremely laggy and makes any work with blueprints infuriating.
What Type of Bug are you experiencing?
Editor
Steps to Reproduce
- In UE 5.8.3, in a blank project, create a BP child class of AActor
- Open the blueprint, right click into the event graph, and type “asd”
- Hold down backspace key to delete the typed text at once
Expected Result
The text is erased immediately and the UI responds instantly
Observed Result

5.8
Platform(s)
Windows
Additional Notes
The ignorance towards performance and optimization in recent UE versions is getting to the point where engine is becoming unusable. In some parts (like Niagara editor) it has gotten so bad it’s getting impossible to get the work done.
