Steam VR Performance Test, LuxMark v3.1
The Steam VR Performance Test measures a system's performance using a 2-minute sequence from Valve’s Aperture Robot Repair VR demo. After running the test, it determines whether your system is capable of properly running VR content at 90Hz and whether or not the visual fidelity can be increased to the recommended level for a given application. Both a system’s CPU and GPU are factored into the score.
There's not much to see here. Like the factory-overclocked 980 Ti and GeForce GTX 1080, the GeForce GTX 1070 hits the peak score attainable in this benchmark.
LuxMark is a cross-platform, Open CL-accelerated 3D rendering benchmark. It's based on the open-source LuxRender physically-based spectral rendering engine, which accurately models the behavior of light and supports high dynamic range. LuxRender also features a number of material types to allow rendering of photo-realistic and artistic scenes. LuxRender is free software, licensed under the GPL, that offers plugins for packages like Blender, Maya, Cinema 4D and 3DS Max. We ran all three of the scenes included with the benchmark using the GPU rendering mode.
In our launch piece, we noted that the GeForce GTX 1080 didn't perform quite as well as expected here. With the newer drivers provided for the 1070, however, OpenCL acceleration appears to be improved. The new drivers wouldn't install on the 1080 though, so we didn't re-test. Even newer WHQL drivers have since been released on NVIDIA's site, however, that likely remedy the situation. Nonetheless, the 1070 performed about on par with the Titan X here, though it trailed AMD's offerings, which offer strong compute throughput.
