@TeleTesselator If you just want to fine-tune your specific one I posted a guide not long ago about some potential visual tweaks from the ini files.
It has some more refined brightness options by adjusting the tonemapper gamma directly but also the strength of specific tones like the mids separately etc
r.Color.Mid=0.43
r.TonemapperGamma=3.2
You could just try that whole ini block I posted in that guide for starters and see if you like it better that way, will depend on your screen ofc (not the steam one as that comes with a pretty big performance hit too, the one I have down below in a collapsed code block)
You can then delete whatever you don’t want or start empty and only add what you want and finetune the numbers to your liking
