Fullscreen mode fixes basically any stuttering for me (in previous patches). However, for some reason, now when the game is in fullscreen it forces the resolution to 1920x1080. I have a 1440p monitor so this isn't really ideal. However when I try to change the resolution it just ignores any changes. I'll get the "are you sure you want to use these settings" prompt, and then it will ask if I want to keep them, but the resolution will not change - not just to 1440p, but any other resolution. I can change the resolution fine in windowed mode, just not full screen. Even forcing settings in the config file didn't fix this.
