I started playing tomb raider 2 on my pc and when i'm going in a very dark area then the screen's brightness goes down automatically, if i fire with a gun and produce some light effects then it goes back to normal for a few seconds and then it goes dark again, this happens only in the darkest areas of the game, like sewers etc, i already turned of adaptive brightness, i tweaked the power save settings, sleep off, power save options off, updated graphics drivers but the problem is still there, anyone knows what i can do to fix this please?
