I never tries those test examples because they are too small to appreciate any GPU acceleration. I hope your benchmark has a reasonable size. > By the way, as a beginner in GPU world, I still playing with the tools... > I'm using a "zotac gtx 460".

GPU compute capability is correct, I am afraid that the GPU memory on the card is not much. QE-GPU is designed to do not crash if the GPU memory is not enough, it simply? run on the CPU as backup strategy. So if the acceleration is very very small it might be because 1) system too small 2) GPU memory not enough for this specific setup > My apologies for subscribe to the wrong list.
