Unwanted HDRP Volumetric lighting has grainy effect based on distance
So what the title says really, ill add some screenshots to show you what i mean. I've setup Volumetric fog and lights in my scene, for example i have a directional light shining down into a hole in my cave, and so volumetric lights, god rays , are being produced which is what i want, however getting a weird issue where when im close to the rays the resolution of the them is perfect, but when im about 5+ units away the rays become grainy/pix elated. its even worse when you move around the scene. It does get worse the further away you get. i have tried fiddling with the lighting & volume settings such as increase the volume fog distance ect with no luck. Hopefully im just missing something simple.
Any help appreciated :)

5+ units away (becomes grainy):
