I can work on faster GPU miner. Wolf's is not that much faster imho. 1.4 vs 2.2mh is a little bad, but unlikely he has enough customers to force price out of profitability for people running OSS miner. Would be nice to get some help from community. Maybe somebody can run NV profiler and figure out where time is spent. I developed this on my laptop which cannot actually run it, so not sure where all the time goes. Obviously optimizing the kernel that takes the most time will buy us the most results.
