@Atlas I also applied all the changes mentioned above, everything looks much sharper, even inside the pit It is now easier for me to read the description on the controls and buttons. The landscape and buildings look much sharper too.
I hope it will make AAR at night easier for me but I did not test it yet
Also I have to mention that I am using BMS in windowed mode. I think I read somewhere that it makes a difference for adjusting the settings. Some will work only in windowed mode and some will not have any effect at all.
This settings deffinitively improved my graphics!
