You know how running games in a lower-than-native resolution in fullscreen upscales the image to the monitor?
WELL BITCH, IT SHOULDN'T HAVE TO
Go into the settings for whatever display driver you have, and there should be an option like the one in the image. Of course, your display driver SHOULDN'T be intel integrated graphics but if you're a poor piece of shit, you won't be able to help that.
The result is a little isolated image in the center of your screen. This isn't actually "fullscreen" in any sense of the word, but it's at least better than windowed mode because for the most part you shouldn't be doing other shit while you play games anyway.
This setting's very good for visual novels and fighting games where you shouldn't want to rescale the image.
