Blurry Textures + Aliasing

Hello!

Ive just set up my Quest 3 with UE5. But if i start my test level, the textures are getting blurry in the distance. Also i have a massive aliasing on some objects. 

Ive gone through all the associated project settings, but nothing changed. Ive tried it with 4k quixel megascans but its still blurry. Any advice?

Thank you!
