Dynamic Super Resolution (DSR)
The picture is pretty self explanatory. Nvidia Control Panel --> Manage 3D Settings. Apply the changes highlighted (only two). For DSR - Factors, you could select all resolutions, however 2x and 4x should be plenty. DSR - Smoothness is set to a default of 33% -- higher is smoother, but blurrier ; lower sharper, more aliased. Some suggest values of 0, 10, 15.
Basically it enables games that support 4K resolutions to be used on 1080 p monitors; better quality but fps can suffer depending on the game. You can also experiment with 'older' games and maybe squeeze out better quality. Nonetheless, pretty cool stuff and more things to tinker with.
