Fps drops when i come close to the mesh

Hi, my fps in the editor drops every time I’m close to the mesh, can you help me where is a problem?

Even when I add more meshes, like foliage it gets even worse

What are your PC specs? What’s the material setup?

Found it! It was becouse of raytracing was ON
