Phoronix published a review on the Unigine Superposition Is A Beautiful Way To Stress Your GPU In 2017, 17-Way Graphics Card Comparison

A quote from the article:

It's already been seven years since Unigine Corp rolled out the Unigine Heaven tech demo and four years since Unigine Valley while in that time while we have seen thousands of Linux game ports emerge, but few can match the visual intensity of these tech demos. In looking to set a new standard for jaw-dropping graphics and preparing to torture current Pascal and Polaris graphics cards as well as future Volta and Vega hardware, Unigine Corp today is releasing Unigine Superposition 1.0. Unigine Superposition is one godly GPU benchmark and is a beauty to
watch.
