you not understand… you can have put 10 000$ in a Screen, the calibrate is do by you…
Do you have calibrate your screen? Each years you need to do that fo to have a file “Color calibrate”, after which screen you have? Oled? Nits?
All is perfect from my side, and I make 3D Graphic since 30 years… I can tell you the Lighting in UE 5 Conan is perfect and in Square Inverse. RAdiosity yes is minimal, impossible to compute milliard of Photons in real time same the UE5 or Unity, it is not Arnold Render or VRAY or IRAY…
In the interest of being open, and honest in my emoji response, I fully empathise with your issue.
I am no expert as to the reasons behind the lighting issues you, myself, and potentially 1000’s of other players are experiencing, but if I may make a suggestion..? I use Radium Torches with slightly darker dyes in them to offer a reduced light with, so far, no eye hurting glare.
