Building an Eyefinity setup is easier than ever, thanks in part to the powerful GPUs we have the choice of, and also the easier-to-stomach pricing of 20~24″ displays. Sapphire, with its FleX, makes things even easier by giving us a card that negates the requirement for a DisplayPort monitor. That 3×1 setup is looking good, isn’t it?

Unigine Heaven 2.1

While Futuremark is a well-established name where PC benchmarking is concerned, Unigine is just beginning to become exposed to people. The company’s main focus isn’t benchmarks, but rather its cross-platform game engine which it licenses out to other developers, and also its own games, such as a gorgeous post-apocalytic oil strategy game. The company’s benchmarks are simply a by-product of its game engine.

Unigine Heaven 2.1

The biggest reason that the company’s “Heaven” benchmark grew in popularity rather quickly is that both AMD and NVIDIA promoted it for its heavy use of tessellation, a key DirectX 11 feature. Like 3DMark Vantage, the benchmark here is overkill by design, so results here aren’t going to directly correlate with real gameplay. Rather, they showcase which card models can better handle both DX11 and its GPU-bogging features.

The latest drivers don’t increase or decrease the performance in any of the games we test, but the performance is decreased a little more notably with Unigine’s Heaven. This is a performance caveat I’d expect to get fixed in the near-future, with AMD’s upcoming Mjölnir releases.
