Playing games in fullscreen mode can provide a more immersive and enjoyable experience. It allows you to focus solely on the game without any distractions from your desktop or other applications. Additionally, fullscreen mode can sometimes improve performance by reducing the amount of resources required to render the game.
There are several ways to fullscreen a game. Some games have a dedicated fullscreen button in the graphics settings menu. If the game does not have a fullscreen button, you can usually press the F11 key to toggle fullscreen mode. You can also use the Alt+Enter keyboard shortcut to fullscreen a game.
