Batman Arkham Origins
Batman: Arkham Origins was recently released in October 2013. It utilizes the Unreal Engine 3, and is an action-adventure game where the player takes on the role of Batman. While it is technically the third game in the series, it is actually a prequel to Batman: Arkham Asylum and Batman: Arkham City.
Batman has a hidden benchmark tool that runs several pre-configured scenes against the video options. This is a great feature to be included and makes it an easy way to make a good comparison across multiple video cards. The resolution was set to 1920×1080, Anti-Aliasing was set to MSAA 2X and DirectX 11 Enhanced features were enabled as all the cards are DirectX 11 compatible.
Benchmark Results: The Sapphire R7 260X surprised me in Batman Arkham Origins. On average, it performed better than the other cards (even though it was only by 1FPS compared to the 7950).
