DONE > Raw: 2767K c/s real, 14573K c/s virtual This might also be 20% of your CPU, without the GPU involved. Notice how the real c/s rate is roughly 19% of the virtual one, which confirms this guess. Real is what you actually get; virtual is what you would presumably get at 100% load of one CPU core (and, from your non-OpenCL benchmark, you know that you could get even more than that). Yet it is nice to see that we have "something" working, even if it performs so poorly at this early stage. Thanks, Alexander
