One of the most impressive graphical options introduced by the beta of Battlefield 4 is the "Resolution Scale" option, that allows you to tweak the internal rendering resolution of the game in order to make the game run faster (and on much slower PCs) via downsampling or to increase the visual  fidelity progressively if you have a really beefy rig by supersampling, without changing the final display resolution.That's something that could already be done with a lot of laborious tweaking on your video card settings, but having it implemented directly into the game is a lot more convenient and accessible to everyone.The option is so useful that I actually wondered if it's going to be included in further games powered by the Frostbite 3 engine. That's why I took to Twitter and asked Frostbite Technical Director Johan Andersson.

(Note: Andersson clarified that he meant "game team" in a further tweet).

So there you have it: the plan is to use the option in more Frostbite-powered games, even if obviously its implementation depends on each team. Hopefully most if not all of them will opt to implement it, because it's a really useful tool to tweak performance and graphical fidelity a lot beyond or below what the usual settings would allow.

For reference, the games (at least those that have been announced so far) that will use Frostbite 3 in the future are  Need for Speed: Rivals, Star Wars: Battlefront, the new Mirror's Edge, Dragon Age: Inquisition, Plants vs. Zombies: Garden Warfare and the next Mass Effect.
