This I think is due to the atmosphere not being disabled when the volumetrics system is disabled even though it might seem like it would be due to being a child of the volumetric lighting section in ImGui there. If you uncheck the "Atmosphere Enabled" box though and then disable the volumetrics that may fix what you're seeing.
This potentially is by design (need to ask the person who worked on it to figure that out), and if that is the case that atmosphere section may have to be moved out to communicate this better, but it's also possible this is a bug and it should be disabled along with the rest of the volumetrics.

It does not rectify the issue. The only reason I have the "Atmosphere enabled" is because it makes it easier to see what the issue is. When that setting is disabled, the entire scene is darker instead of that area with the sphere.
Yeah unfortunately disabling the atmosphere will also disable the skybox right now I think...or something like that which might be what is causing the darkening overall. Needless to say though the system has some issues right now so it'll have to be investigated.
Tracked as REMIX-4142.

Just for info, I'm not using the remix skybox. Just tested recent version of dxvk-remix 795, it appears the issue is still present:
I recently made a fix which should address the issues with disabling volumetrics not working properly, found in this commit here: https://github.com/NVIDIAGameWorks/dxvk-remix/commit/0f974386ddc3c20680ae3391cd98c50e1d402778 There's also a commit done a few days ago which should fix some issues with the atmosphere causing that strange spherical dark spot.
Do you think you could try a Remix version based off that commit (or later) and see if it addresses the issues you are seeing?

Excellent, seems fixed!
