Battle Forge is the free-to-play RTS from Electronic Arts. It offers a steampunk/fantasy RTS experience, where armies are build based on "decks" of cards similar to the Magic: The Gathering card game.

Battle Forge is one of AMD's spotlight (my terminology) games, as it offers both DX11 and proper Eyefinity support. The game offers a number of DX11 features, and a wealth of options for tuning performance. Specifically, Battle Forge uses DX11 and Shader Model 5.0 to compute HighDefinition Ambient Occlusion (HDAO). For our tests we maxed out all of the settings and forced DX11 through the config.xml file.

The Radeon 5870 approaches 60fps in a single widescreen, at max settings. A single card will get close to 30fps in 3x1-L Eyefinity, and push past with a pair. A pair of cards also average 30fps in 5x1-P.

As seen with AvP, the decrease in fps is less (as a percent) than the increase in pixels when moving from 3x1 to 5x1.
