God damn I fucking hate adaptive brightness. It's the most retarded shit where when you have something bright on the screen, the brightness will go up and if you have something dark on the screen, the brightness will go down. Supposedly this is to "conserve energy" or some shit. It's so retarded that windows had to remove it, but unfortunately your graphics card will still have a setting for it, AND YOU HAVE TO RESET IT EVERY TIME WINDOWS UPDATES.
I have Intel and they have 3 different control panels for settings, all of which I never use until windows decides to update out of nowhere and I notice that I can't see shit suddenly. I forget which setting that I have to change to make it stop because there is legitimately like 7 different places where you can enable/disable adaptive brightness and a majority of those don't work since being removed from win10. I go online for help and the top results coming out this year will still parrot the same outdated information. I spent like 40 minutes going through them all and reaching dead ends for all of them.
I was really fucking close to never touching my laptop again because of the annoying brightness changes until I got the epiphany that maybe I just need to toggle the battery settings in the intel control panel to ON then OFF again. It fucking worked. The fucking thing was displaying the wrong setting for some dumbass reason and caused me to waste a half hour because that was the first setting that I checked, making me think that I really needed to toggle something else instead.
