The problem is not in the miner. The problem is in nvidia drivers. You have to use old drivers on Win10, new drivers don't work as they must do. But old drivers don't support cuda 7.5 which is used by the miner. So I have to release at least two versions of miner - for cuda 7.5 and for cuda 6.5. It's annoying, especially because I see less hashrate on cuda 6.5.
