Ok so, when i launched the fallout 4 launcher and i wanted to choose the screen resolution on full screen then i noticed that i can't choose aspect ratio (mine is 4:3) so the aspect ratio tab is greyed out and the resolution tab is blank so i start the game anyways and there are some interference bugs like out of placed letterboxes or something like that but the huge problem is that whenever i try to picklock something while on full screen the background blurs out (like it should) and there is no lock on my screen but i can hear the sound of how i pick the lock by pressing A and D. So i need to change from full screen to windowed so i could pick lock it. I play the game on 800x600 cause my pc isnt that great but the game is playable not to metion the picklock bug.
