UE5 : Trying to profile, but need some help (CPU bottleneck ?)

Hello !

Got some issue to profile, and understand my performance issue.
The map is a vast landscape, with a huge bunker structure under the landscape.

When i’m looking away from the bunker and be outside, performance is fine (120 FPS). When i’m looking to the bunker, trough the landscape, or be in the bunker, performance drop (60 FPS).

99% of the mesh are nanite, here all the information i’ve got, don’t hesitate to ask me if you need more logs/stats

I will love some help to understand from what come the issue, visibly it’s the draw who bottleneck.

Note : stats here are taked in editor, but doesn’t really change anything in package build or in standalone. I mean, it’s reduce a bit the issue, but it still here.

Hi did you have any luck solving this? I am facing a similiar issue with a large landscape

Unfortunately, no.
