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

Christian B, if I hear anything from Nvidia, I will post it here, so far nothing. I'll try the newest drivers when they are released. At the moment I have found a way with Group Policies in Win 10 to not allow updates to drivers, seems to be working. I'd like to update all my cards so they can hash faster, except really I hash some on these old PCs because they were setting around and a few dollars in digital coins for just setting up a few batch files seems worth it to me. Kind of fun to see them hashing coins, even though they are getting long in the tooth.
