Around one year after version 1.0, the new version of LuxMark, an OpenCL benchmark based on LuxRender, is available. LuxRender is a physically based and unbiased rendering engine. Based on state of the art algorithms, LuxRender simulates the flow of light according to physical equations, thus producing realistic images of photographic quality.
This new version of LuxMark 2.0 comes with a new rendering engine with multi-platform OpenCL support, two new benchmarks and the ability to run the benchmarks on selected compute devices (GPUs and / or CPUs).
Quick test:
Scene: Luxball
Scene: Luxball – Score: 7872 points (Radeon HD 6970)
Scene: Luxball – Score: 3120 points (GeForce GTX 460 + GeForce GT 520)
Scene: Sala
Scene: Sala – Score: 844 points (Radeon HD 6970)
Scene: Sala – Score: 456 points (GeForce GTX 460 + GeForce GT 520)

Sadly, Nvidia’s OpenCL 1.1 ICD performance is still broken and Fermi lags behind in this bench.
GTX 570 @ stock :
Luxball scene – 5526 points.
Sala scene – 820 points.
seems to catch up with hd6970 as scene complexity / triangles count raise.

The LuxMark 2.0 has a memory problem on Linux. After running benchmark several times, it ate more than 5G memory included swap which almost made my machine crash. I guess it allocates resources for each benchmark and releases them only after closing application.
Nvidia is not active on OpenCL. And they care more about CUDA and latest openACC. I worry a little about the future of OpenCL support from Nvidia.
Boy these scala images look extremely noisy definitely not enough samples per pixel you probably need at least 8 times more samples on these.
Guess that’s the problem with brute-force MC algorithm
Crashes on my computer.

@JeGX an @guys:
ALERT! because OpenCL 1.1 driver is 1.5x slower than 1.0 (275.33WHQL). Therefore, please you should downgrade to 275.33WHQL to try LuxMark. 🙂

Why is Luxrender so slow and Octane so fast?
