How to optimize performance with World Partition in UE5?

Hi everyone,
I’m currently working on an open-world project in Unreal Engine 5 using World Partition to manage my level. However, I’m facing some performance issues, especially when streaming in and out cells on lower-end hardware.

I’m looking for advice or best practices on how to:

  • Reduce loading times when moving between regions
  • Get better control over which actors are streamed in/out
  • Maintain stable frame rates during traversal

Has anyone successfully optimized World Partition in a large world setup? Any tips, documentation, or personal experiences would be greatly appreciated. Thanks in advance!

Hello there @xey89888 !

Indeed, there are multiple resources that cover performance handling with World Partition.

I would suggest starting with the world building guide, it should get you covered on best practices, and a lot of basics for creating worlds effectively. After that, check the documents for WP itself, and for Level Streaming, which will be critical for an optimal performance:
