[UE 5.4] Weird shadows jittering / flickering despite of distance

Development Rendering
1

Hello,

I’m facing an issue that I can’t resolve, despite all I could read of this forum and others.

My project is under Unreal 5.4, and I don’t know why but shadows on some buildings, and on the road are jittering / flickering :

I’m not using Lumen (as far as I know), my ScreenPercentage is at 100%, I’m using stationary directional light with baked lights (tried a lot of different settings I saw on this forum), virtual textures, etc …

I also tried new plugin GPU Lightmass to build lights, it does the same as CPU lights building.

And finally, I tried to activate Lumen GI on my Post Process Volume, and it does the same too.

I’m a bit confused, I saw many other people facing similar issues, but it seems like a few get a solution :frowning_with_open_mouth:

Thanks for your help :pray:
