So how do you make a game run in more than 720p on a 720p screen? |
A games rendered resolution is independent of the displays resolution.
Even games which claim "1080P" on the Playstation 4 don't have everything running at 1080P.
Shadows have their own resolution, Textures have their own resolution, even light shafts might run at 720P even if the game is outputting 1080P.
But to answer your question in a more specific manner. There is this thing known as "Down Sampling" otherwise known as "Super Sampling" many forms of Anti-Aliasing actually fundamentally take a similar concept to remove aliasing in games.
