UNIGINE Superposition is a freeware OpenGL graphics benchmarking suite for Linux and Windows. It runs a series of highly detailed graphics scenes and produces a score. It is useful for comparing graphics card performance as well as performance between different kernel and Mesa versions. There are also a mini-game included.
UNIGINE Superposition is freeware but it is not free software. You will have to submit to a "Superposition Benchmark End-User License Agreement" found in the
docs/ folder. It states that commercial use is only allowed by corporations who purchase a license. Private individuals can download and use the software relatively freely: Everything but de-complation is allowed.
Features And Usability
UNIGINE Superposition starts with a configuration screen where you can choose presets for different resolutions and low, medium and high settings depending on the resolution. It is also possible to choose "Custom" and configure various settings.
The benchmark runs 17 different scenes and produces results screen with a score and low, average and high FPS numbers.
The results the Linux version of UNIGINE Superposition can be compared to results from the Windows version to get some sense of graphics performance but the numbers will very because of the huge under the hood differences between the Windows and the Linux version: the Linux version uses OpenGL while the Windows version uses DirectX. The results from one Linux machine can be compared against results from another Linux machine to get a fairly accurate sense of their relative performance. Comparing results from the Linux version with the Windows version says something but the results are not directly comparable in the same way two Windows results or two Linux results can be compared with each other.
UNIGINE Superposition runs perfectly on any GNU/Linux machine with Mesa installed. You do not need to use proprietary drivers to run it (performance will obviously vary depending on what driver you use).
The benchmark includes a "mini game" which is not at all interesting. It is mostly something they put in there to show developers what the their game engine can do.
See Graphics benchmarking software for a list of mostly closed-source proprietary alternatives. There are no simliar free software alternatives that are this advanced. glmark2 (and the vkmark Vulkan implementation) does not come close, it is a very simple benchmark in comparison.
UNIGINE Superposition can be downloaded from benchmark.unigine.com/superposition. It is freeware, not free software, so you can download if and run it free of charge but you can not have the source code. The UNIGINE Superposition benchmark is a hefty 1.6 GiB download. Luckly, there is a BitTorrent option with enough seeds to fully utilize most connections.
