UE5 is not well optimized?

Sorry I could not help. Any chance you could link some of the threads you mentioned?


Also, there is this section of the forum where you can provide feedback, constructive or otherwise:

https://forums.unrealengine.com/tags/c/general/feedback-requests/50/unreal-engine

It has a voting system, perhaps if enough folks experience the issue, it can then be addressed.

Good luck!
