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 ATI's spotlight (my terminology) games for the HD 5000 series cards, 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 test is actually quite strenuous with the number of objects, effects and particles on the screen at one time. In most instances, the scaling is averages 80%. The two instances with considerably lesser scaling are the HD 5850 and 5770 at 5760x1200.
