One of the things that's interesting is that you can scale the rendered resolution. So, you can set your graphical resolution to say 1080p but then set the rendering scale to 70%, so it upscales the image, like what consoles do.
Never seen the option in a PC game.
Running a 7950 at 1200p and the game's smooth as silk. The cutscenes are jarringly off and I've found the main menu has some real performance issue if I drop back to it from the game.
It's actually a built in feature of the Frostbite Engine. So Battlefield 4 (and I assume Plants Vs Zombies: Garden Warfare) has it and presumably most of EA's non-sports games going forward will have it since all Bioware, DICE, and Visceral games that are currently announced make use of that engine.
