HDRP Volumetric Fog jitters when moving the Camera
How to reproduce:
1. Open the attached project “FogJitterFinale“
2. Open the Scene “Test“ (Assets)
3. Place the Scene and Game view windows side-by-side
4. Move the “Main Camera“ Camera in the Hierarchy away from the “Fog“ GameObject
Expected result: Fog doesn’t jitter in the Game View
Actual result: Fog jitters in the Game View
Reproducible with: 14.0.3 (2022.2.0b7), 15.0.0 (2023.1.0a9)
Can’t test with: 10.10.0 (2020.3.39f1), 12.1.7 (2021.3.9f1), 13.1.8 (2022.1.15f1) (Errors in the Console)
Reproduced on: macOS (12.5)

Resolution Note:
Depending on your scene, the volumetric system needs to be finely tuned to be able to perform both in terms of speed and visually.
The scene in the repro project uses a high detail 3D procedural noise and it's very hard to tune the volumetric system system to render those kind of fog since they need both high resolution and high depth slice count.
There are multiple ways of reducing the jittering in your scene:
- Increase the resolution % of the fog, though you may go over budget
- Reducing the Volumetric Fog distance and tweaking the Slice Distribution Uniformity
- Modifying the noise in parameters to be less detailed and smoother. Scale the amount of detail based on the camera distance so that high frequency noise disappear in the background.
