LuxMark
LuxMark is a free, cross-platform benchmark for rendering workloads, based on LuxCoreRender and built with the LuxCore API.
What LuxMark is
LuxMark is a free, cross-platform benchmark for rendering workloads, based on LuxCoreRender and built with the LuxCore API. It measures OpenCL and C++ rendering, GPU and CPU path tracing, hybrid GPU-and-CPU path tracing, and C++ bidirectional path tracing. Path-tracing tests can run with or without a global illumination cache, while a separate stress mode places a heavy load on hardware to check reliability. LuxMark validates results by checking rendered images and scene source files. It supports custom test profiles and command-line or automation use; the command line supports FOOD, HALLBENCH and WALLPAPER scenes. Intel OpenImageDenoise is included for image comparison, but its CPU-only denoising task does not contribute to benchmark results. 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 GPL-licensed, and the project is maintained by volunteers around the world.
Good
- Benchmarks GPU, CPU and hybrid rendering workloads.
- Includes a separate hardware stress mode.
- Supports custom test profiles and command-line automation.
- Available on Windows, macOS and Linux.
- Free benchmark software.
Watch out
- v4.0alpha1 is a pre-release.
- CPU-only denoising does not count toward benchmark results.
Who it suits
LuxMark suits people comparing rendering workloads across Windows, macOS or Linux systems, or applying a heavy rendering load to check hardware reliability. Custom profiles and command-line support may suit users who want configurable or automated runs.
Verdict
LuxMark focuses on rendering benchmarks, with several path-tracing modes and a separate stress option. Check the release status if choosing between the listed versions.
