Lumen-torn, aliasing shadows. Can anyone help?

I have problem with lumen virtual shadows. Shadows are aliased and the look ugly on low poly meshes, in other projects everything is ok on for example quixel megascans. This happen only when i have directional light in my scene. In addition it happens also when lumen is turned off and engine is using shadow maps

I have tried:
-changing the directional light to new, default one
-changing the lightmap resolution in mesh settings
-building game

My shadows:

My scalability settings:

My directional and sky light settings:


My rendering engine settings:

PostProcess settings:

Can anyone help?

Try disabling virtual shadow maps

I typed r.Shadow.Virtual.ResolutionLodBiasDirectional -10 in console and it works, but thanks for help.
