DSR lets you crank up the internal rendering resolution when you’ve got spare performance, further improving the quality of your graphics. For example, if you own a GeForce GTX 1080 and use a 1920x1080 screen, you’ll be able to render Titanfall 2 on your graphics card at 3840x2160, and then automatically downsize the picture to fit your 1920x1080 monitor, greatly enhancing image quality.
