It puts up the GPU info, including temperature, frame rate, etc. as the animation runs. I was thinking this would make a nice reference for those who were having (or suspect) graphics problems. It quite similar to what could be done with other game engines since you can navigate through the scene. It has day/night/day cycles, birds (I think I saw that), stars, rain, fog, etc. And there's a free version.
I'm getting a new gfx card -- GTX 760 oc'd -- tomorrow and was interested in comparing my current card, especially temp and frame rate.
{EDIT}
Here's what the benchmark looks like. There's 18 different tests it runs through.
