What LuxMark is

LuxMark is a free, cross-platform benchmark for measuring rendering workloads, built on LuxCoreRender and the LuxCore API. It evaluates OpenCL and C++ rendering, including GPU, CPU, and hybrid GPU-plus-CPU path tracing, as well as C++ bidirectional path tracing. Path-tracing tests can include a global illumination cache or run without one. A separate stress mode puts a heavy load on hardware to check reliability. LuxMark validates results by checking rendered images and scene source files. It includes Intel OpenImageDenoise for image comparison, though its CPU-only denoising task is excluded from benchmark results. Users can create custom test profiles and run tests from the command line or through automation; command-line scenes include FOOD, HALLBENCH, and WALLPAPER. LuxMark runs on Windows, macOS, and Linux. The repository lists v3.1 as the latest release and v4.0alpha1 as a pre-release. Its source is released under the GPL license. The project is maintained by volunteers around the world, and its site links to forums, Discord, a wiki, and a bug-reporting forum.

Who it suits

LuxMark suits people who need to benchmark rendering on Windows, macOS, or Linux, including GPU, CPU, and hybrid workloads. Custom profiles and command-line automation make it relevant for users who want configurable or repeatable benchmark runs.
