i am trying to set the game to 1080p fullscreen and when i do this it just shows up in a small little rectangle on the top left of my screen. i try pressing alt+enter and it just switches back and forth from the small rectangle in the top left to windowed mode and wont adjust to the full size on my screen. i have updated all drivers and software on my windows 10 pc. my pc res is set to 2160 but when i try to set the game to that the menus lag not the gameplay and the menu and text size is so small i cant even read it.
EDIT- not sure how but now game launches in full screen on 1080p. i think it was just a problem bc it was the first time i launched the game and now it is fixed. could be bc i used geforce experience to set setting to optimal.
