Hear me out. A few games have shader installations that will usually apply any new settings you put down AFTER you restart the game, and a lot of other games have graphics settings that will only apply after you’ve rebooted the game.
I don’t think it would cost developers ANY amount of money or any significant development time to add a “Reboot game” button (or toggle) every time the player presses the quit button, or give the player a prompt every time they change a setting that requires a game restart (like in both PC versions of GTA V).
I also think ANY game should have a “full potato” mode capable of running in older computers with NONE of the fancy graphics stuff that we have access to today, despite having a decent computer now.
Some games minimize and try to lock your mouse to the game if you alt tab out. Windowed mode makes it pretty much seamless, pain free. No difference I ever found, just easier to alt tab out and check a map, take notes, pause and watch a video.
