LuxMark is a OpenCL benchmark tool. The idea for the program was conceived in 2009 by Jromang. It was intended as a promotional tool for LuxRender (to quote original Jromang's words: "LuxRender propaganda with OpenCL"). The idea was quite simple, wrap SLG inside an easy to use graphical user interface and use it as a benchmark for OpenCL. After Anandtech adoption of SLG as OpenCL benchmark, the code was finally written.

After a year from the release, LuxMark v1.0 has been widely used as OpenCL benchmark by AnandTech, Tom's Hardware, Vr-zone and other sites. AMD has used LuxMark as one of the 5 GPU computing benchmarks to present the new HD7970.

LuxMark v2.0 includes SLG2 as rendering engine with Metropolis Light Transport, Multiple Importance Sampling, Image reconstruction done on the GPU, support for multiple OpenCL platforms (i.e. Nvidia users can use Intel or AMD CPU device) and many more new features. The new features rise the complexity of the benchmark of nearly one order of magnitude and it should be able to put some serious stress on the new generation of GPUs. The capability to submit results to a centralise WEB database looks like the most interesting new feature of LuxMark v2.0:

A special thanks goes to all people at LuxRender GPU Acceleration Forum that have contributed with end-less testing, hints, bug reports, etc.



  • Open source
  • 100% OpenCL
  • Cross platform (Linux, MacOS, Windows, etc.)
  • Complex/real world code used as GPU computing benchmark
  • Support for OpenCL GPUs-only, OpenCL CPUs+GPUs, OpenCL CPUs-only and native CPU-only benchmarking
  • Support for Interactive mode
  • Easy to run
  • Multiple scenes usable as benchmarks

New in LuxMark v2.0:

  • Totally new rendering engine based on SLG2 with Metropolis Light Transport, Multiple Importance Sampling, Image reconstruction done on the GPU, ecc;
  • Multi-platform OpenCL support;
  • 2 new benchmark scenes, for a total of 3 benchmarks with a raising complexity (~200,000, ~500,000, ~2,000,000 triangles);
  • Run the benchmark only on the OpenCL devices you selected on the device panel;
  • Added the possibility to submit the scored result to a centralised result database:;


Windows 32bit executables:

Windows 64bit executables:

Linux 64bit executables:

MacOSX 64bit executables for Intel-Macs:

NOTE: there is a known bug in some old NVIDIA drivers when using the 32bit executable with Windows 64bit, just use the 64bit executable to fix the problem.

Benchmark Scenes

Complex benchmark: Room

Room is a 2,000,000+ triangles benchmark. This scene has been designed by Mourelas Konstantinos "Moure" ( Note: Room scene is extremely complex and is available only on 64bit executables. Old and/or low-end GPU may be unable to render this scene.

Medium benchmark: Sala

Sala is a 488,000+ triangles benchmark. This scene has been designed by Daniel "ZanQdo" Salazar ( and adapted for SLG2 by Michael "neo2068" Klemm.

Simple benchmark: LuxBall HDR

LuxBall HDR is a 262,000+ triangles benchmark.

Result Database


If you have a valid LuxRender forum account, you can submit your results to the LuxMark result database: The database offers online real-time browsing, searching, average results, top 20s and many more features.

A list of old LuxMark v1.0 results is still available here. Note: even if LuxMark 2.0 includes LuxBall HDR scene, you can not directly compare the results of the 2 different versions because of the totally different rendering engine.
