However, the game is actually being rendered as a window - without title bars and above your task bar, but a window nonetheless. When you select this mode, the game will take up your entire screen, making it appear as if you were using Full-screen mode. Use Full-Screen Windowed Mode: Full-screen windowed mode, also referred to as 'Full screen (Windowed)' or 'Windowed (Fullscreen)' mode, compromises between the two.A windowed game probably runs at a lower resolution than a full-screen game, so you're gaining some more performance there - at the cost of a smaller game screen with less graphical quality, of course. However, you can more easily switch between windows. Games running in a window won't have exclusive access to your graphics hardware, so they won't perform quite as well as they would in full-screen mode. Play in Windowed Mode: Games often have a windowed mode, where they render themselves in a window on your desktop.There are several ways you can make this happen: Let's say you want to play a game but you also want to Alt+Tab and use other windows without the risk of crashes or delays while switching. How to Quickly and Safely Alt+Tab Out of a Game When you switch back to the game, the game has to restore itself and take control away from Windows. For a variety of reasons - especially problems with the way some games are coded - the game may encounter a problem while doing this. It has to minimize the game and start rendering the desktop again. Windows doesn't just have to switch from one window to another when you press Alt+Tab.

This means you can squeeze the most gaming performance out of your graphics hardware by running the game in full-screen mode, and that's why games run in full-screen mode by default. When a game runs in full-screen mode, it can gain exclusive access to your graphics hardware - this is known as running in 'Exclusive Mode.' Windows won't render your desktop in the background, which saves on hardware resources. The real question here is why games run in this full-screen mode in the first place, if the full-screen mode itself is a problem. But full-screen mode seems to be different - full-screen games can't be Alt+Tabbed out of as easily. This isn't a problem when you play a game in windowed mode, where you can Alt+Tab easily. It's not just pressing Alt+Tab that's a problem - pressing the Windows key may do the same thing, as it takes you out of the game and back to the Windows desktop. Why is Alt+Tabbing Out of a Full-Screen Game So Problematic?
