[UE4.27.2] Horizontal Plane Texture blurring

Hello there. I have an issue: The texture of horizontal Plane (floor) is weirdly blurring over distance, in both Editor Viewport and in Game. Vertical Plane (wall) is rendered normally. Obviously i don’t want my scene to look like this. Is there a way to avoid this blur?

It’s from anisotropic filtering, r.MaxAnisotropy 16 should improve it.

Oh, thanks a lot! I could try, but I am not aware what it is, and where to set it.
However, i just figured out that my [Settings->Engine Scalability->Textures] were set to “Low”. I thought it will reduce the texture sizes in the built game, but instead it just blurring them. Technically, setting it to “High” has solved the issue.
