Setting it higher than 0 will make the reflection to strong. Value 4 did had an effect on a light bulb. Setting value 3 to 0 will result in a white screen. Value 2 and 3 also don't seem to do anything. Setting this value to high will result in a black screen. They have no impact on the games visuals (or maybe they have in situations i haven't encountered yet).
If you want you can tweak the console commands in the 1.txt file yourself. This means that you need to reapply the console commands everytime you start the game. Once you close the game, all values will switch back to 'normal'. You can even go back to the main menu and load a savegame from there. Once you loaded a savegame for the first time, it doesn't matter if you load another savegame. This is very important, because if you do it before, your screen gets black once your savegame is loaded (restart is the only fix).
> typ 'bat 1' AFTER you loaded a savegame for the first time. > Put the file in the fallout4.exe folder I found a way to fix the brightness issue of AFR friendly mode. I noticed that i'm only repeating myself, so i just going to post my fix in a new thread. Some people seem to have missed my post in the fallout 4 performance thread.
