Unigine are a busy little company. It makes games, like 2012 RTS Oil Rush. It makes PC benchmark tools. And it also makes engines.
We're looking at a combination of the latter two here today, as this vdieo takes us on a sweeping tour of an enormous, 64sqkm wooded landscape that looks just perfect for, say, something like a big fantasy RPG.
What's cool is that, unlike more passive benchmarks, this acts as a demo for the engine itself, letting you either walk or fly around the environment in real time.
