I made some changes to the default hlsl.json values successfully.
I had to modify the radial_converge values from 2 to 4 decimal places to get the equivalent level of granularity as the Windows default scale and was able to get it set up exactly how I remember it on Windows
Thank you so much once again for the guidance!
Adding a before-and-after screenshot and will upload the tweaked hlsl.conf in a bit if anyone else finds it useful.
