So what is fullscreen mode? It gives your game exclusive control of the display. This means Windows steps aside, dedicating most of your system graphics resources to the game itself, which can help you eke out more performance from the most cost effective AMD and NVIDIA graphics cards . As a result, fullscreen often provides slightly better frame rates, lower input latency, and overall smoother performance. This is why esports professionals and competitive gamers tend to stick with fullscreen.
