Anyone using Windows 10 with GTX 480 or 580's with the 355.60 seeing hashing rates much slower?  On ccMiner21 mining dash I went from 1.4 Khash/s to 0.9 with the 480, and from 1.8 to 0.9 with the 580.  I have asked nVidia about it and reported it as a bug so at least they know about it I am not expecting much since they are older.  Interestingly enough the GTX 680 hashes away at it's normal 2.9 Kh/s with the 355.60.  Any help would be appreciated. It really would not even be a problem and I would just run the earlier drivers and be done with it, except as Windows 10 is force installing, even though I have disabled it from doing so, it still force installs 355.60 and I have to revert to 340.xx series to get back good hashrates. Are there any versions of some underlying software that I might be able to update?  For example Microsoft C++ redistributables or something?  Seems NVidia or Microsoft may have changed something to make them hash so much less. Thank you for any thoughts, Vvrroomm
