Viewport and Render in very low quality (UE5)

I’m just learning Unreal Engine and doing everything according to tutorials. And I want to make a scene with a forest. But I have a problem with the fact that in the preview and in the render I have everything in low quality. The trees have no shadows, it looks Low poly. I even set Engine Scalability to Epic, and LOD in the sequence to high quality.

But for example, the demo scene with “Rain Forest Pack” looks like low poly, without shadows and details. Even in the render through Movie Render Sequence I get low quality.

Can you advise what to do in this situation, how to achieve good graphics. I tried almost all the tutorials from youtube.
