Performance issue envolving Metahuman

[Leandro_O (Leandro_Oliveira)]

Hi. I´m not sure if this is the better category for this.
I´m using Unreal 5.1 and my level has the following stats:

This level has one metahuman and a lot of assets. My machine is an AMD Ryzen 9 5900, RTX 3060, 64Gb RAM. I´m using Hardware Raytracing and the performance of the scene is poor for manipulating things. But, if I hide the metahuman, everything flows smoothly.
When I upgraded to 5.1 version, I noted a warning inside Metahuman Blueprint:

So, I´m not sure if this performance problem is caused by Metahuman.
I have other projects with the same Metahuman, in Unreal 5.1, and I don´t have this performance issue, but I admit the scenes are lighter than this I´m working on.
I know this is not a simple question, but there´s a tool or information where I can search for a solution that points to me the problem?

Well, I found the issue: many lights with Source Radius above 0. If I disable ray trace for that lights, the performance is increased. Of course… But I think there may be something more since the project was converted from 5.0.3.
But it´s ok. I´m continuing to learn about Unreal.
