So my issue is some games won't let me enter custom settings when I choose one then apply it flickers from my selection back to what it was. I have tried rolling back drivers, a clean install of Geforce, checked and unchecked boxes in settings but nothings working. I just want to play Darkest Dungeon not in 2K laggin at 10 FPS. I also have a Gsync Monitor I am not sure if that adds anything to this situation. Any help would be greatly appreciated.
