No, that is the hybrid rendering mode, look for PathGPU rendering mode (the sources are in the pathgpu directory: http://src.luxrender.net/luxrays/fil...uxmark/pathgpu). It is the one used in LuxMark.

wow AMD's opencl drivers deliver amazing perf improvement.. almost on par with a GTX 580

Here's what I get on an A8 Llano at 23x152 (just CPU-Z since GPU-Z doesn't show anything helpful on this chip).
