Shadows are flickering when large Scale GameObjects are far away from the Camera and "Ray Traced Shadows" are enabled in the "Light" component of the "Sun" GameObject
Reproduction steps:
1. Open the attached “IN-55509 RTX Shadows Bug 2.zip“ project
2. Open the “OutdoorsScene”
3. Select the “Terrain” GameObject in the Hierarchy
4. Focus on the “Terrain” by pressing the “F” key while hovering over the Scene view with the mouse, so the whole “Terrain” is clearly visible
Expected result: Shadows on the “Cube” GameObject are not flickering
Actual result: Shadows on the “Cube” GameObject are flickering
Reproducible with: 2021.3.31f1, 2022.3.10f1, 2023.1.16f1, 2023.2.0b12, 2023.3.0a8
Reproduced on: Windows 11 Pro (22H2)
Not reproduced on: No other environment tested
Notes:
- In the 2022.3.10f1 and newer Unity versions, the ray traced shadows are also flickering on the “Terrain” GameObject
- Reproducible in a new project
- Reproducible in Player
- Ray tracing is only supported in HDRP with the D3D12 Graphics API

- “FMOD failed to set the software format to the custom sample rate…” warnings are thrown as System Sample Rate value is being changed in Audio section of Project Settings window

Resolution Note:
Please use Ray Bias and Ray Distant Bias settings in the Ray Tracing Setting in your main Volume Settings. A value of 0.1 for both seems to work very well.
