The main purpose of software is performance and stability testing for GPUs.

Users can choose a workload preset, Basic or Extreme, or set the parameters by custom.

The benchmark 3D scene is a steampunk-style city on flying islands in the middle of the clouds.

The scene is GPU-intensive because of tessellation used for all the surfaces, dynamic sky with volumetric clouds and day-night cycle, real-time global illumination, and screen-space ambient occlusion.

Heaven and other benchmarks by UNIGINE Company are often used by hardware reviewers to compare performance of GPUs[1][2][3] and by overclockers for online and offline competitions in GPU overclocking[4][5].
