Shadows disappear at a distance even with correct settings (UE 5.5)

[Mgm3d]

i everyone, I’m having a strange issue in Unreal Engine 5.5:

Shadows disappear at a distance, even in a completely clean scene with correctly configured Directional Light, no Lumen, and all scalability set to Epic.

What I’ve already tried (without success):

1. Disabled Lumen (in Project Settings and via .ini)
2. Directional Light with correct settings:

• Mobility: Movable
• Cast Shadows:
• Use Cascaded Shadow Maps:
• Dynamic Shadow Distance: 50000+
• Atmosphere Sun Light:
  Console commands tested:
  r.ForceLOD 0
  r.ViewDistanceScale 10
  r.StaticMeshLODDistanceScale 0.01
  r.FoliageCullDistanceScale 10
  r.Shadow.CSM.MaxDistance 100000
  r.Shadow.DistanceScale 10
  r.Shadow.RadiusThreshold 0.01
  r.AllowOcclusionQueries 0

1. Enabled Ray Traced Shadows (same result)
2. Checked all World Settings and Post Process Volumes
3. Created new test scene (cube + plane + Directional Light only) — shadows still disappear when camera moves away
4. No foliage, no Niagara, no forced LODs
5. Updated GPU drivers (using RTX 4080 SUPER)

What I need to know:

Is this a new default behavior or a hidden parameter in Unreal 5.5?
Or is it a known issue in 5.5 with specific GPUs?

If anyone can reproduce or confirm this, it would help a lot. Thanks!
