It's easy for small bugs and little mis-optimisations to make their way into your levels, building up over time. They accumulate into something much bigger, negatively impacting a player's perception of your game almost as much as a single, larger bug could. I like to think of the analogy of: 

Death by 1000 cuts, or in our case preventing Death by 1000 bugs

Manually checking every actor in your level for issues is time-consuming, tedious and so unrealistic. It becomes like searching for needles in a haystack. This Level Optimise tool is:

Designed to help you quickly find those needles (issues) in the haystack (level)

Here are a few of the key performance issues this tool can help you identify, allowing you to claw back FPS:

• Lights with no Max Draw Distance set
• Lights with Cast Shadows enabled
• Static meshes with Nanite disabled
• Skeletal meshes with no LODs

... and many more!

NOTE: The tool doesn’t make any edits to your level or project; it only reads your assets to generate logs about potential issues that you could look into. I thought this was important because every project is unique and highly contextual. What's correct for one level may not apply to another. For instance, deciding which lights should have cast shadows enabled / disabled to help balance visual fidelity and performance.
