I see in the editor the possibility to use different resolution for the Game view and it’s work pretty good, like set the 4K resolution for an 1080p screen.
But how that’s work ? Is it possible to do that for build version with script ? If yes how ?
Why would you want to do that for the build? It’s a waste of resources.
All that happens is the game is rendered at 4K, and then downscaled to fit inside whatever the resolution of the game window is. It is not possible to actually display the game at a higher resolution than your monitor physically allows.
