@perrry i wonder, i see you fly in 4k, is it with dsr?
And if not, is your monitor is real 4k
Because if it is open dsr in graphics card controlpanel and set a higher resolution in user interface generals and set lower secondaryscale in usercfg.opt like 0.400000 or 0.600000 and in the ui again set renderscale to 3840 2160 or a little bit higher
You get something like this

I know it is a bit on the brightside because of hdr but it is all tune able in freestyle
The thing im trying to point at is with a fine resolution there is better management of colouring in the sim. I hope i express myself clear enough, but maybe you and ofcourse others can look into this
