Results: Batman Arkham City
This relatively new title is based on the Unreal 3.0 engine. A few more bells and whistles have been added to the PC title, and it does leverage some DX11 functionality. Settings were maxed out with 4X AA and 16X AF enabled. The built-in benchmark was used.
There are a few interesting things to gather from this. The R7870 had the highest minimum frame rates at the lowest resolution, with the GTX 670 trailing well behind. On the other hand, the GTX 670 had the highest average framerates for all resolutions. At 2560×1600, the lead was quite significant for the NVIDIA card (and all minimums were about even).
