Short description of problem

The shadows in Blender 2.80 EEVEE rendering engine look choppy and low resolution. The further the lamp is from the object the worse the shadow looks. There appears to be a bumpy/choppy edge to all the shadows and there is no way to increase the quality or sharpness of the shadows. The result is every scene having unrealistic and inaccurate lighting and shading.

Exact steps for others to reproduce the error

From File:

  1. Open .blend file.
  2. Look at the shadow.
  3. Switch between supported lamp types.
  4. The shadows should appear choppy and bumpy.

From Scratch:

  1. Open Blender.
  2. Place a plane in the center of the grid.
  3. Scale the plane by 10.
  4. Move the default cube up by one Blender unit.
  5. Delete the default lamp.
  6. Place a lamp pointing in the direction of the cube.
  7. Increase the brightness of the lamp as needed so that it will cast a shadow.
  8. Look at the shadow.
  9. Switch between supported lamp types.
  10. The shadows should appear choppy and bumpy.

Confirmed here, this is the shadow:

Unfortunately, this is a side effect of using octahedron mapping for shadow map and using a low resolution

Increasing the resolution should give better result (this setting is still not there).

Supporting cubemaps array will fix this on hardware that supports it.
