Since the 384th era of Ethereum mining, many have noticed a decrease in the hash rate of their mining rigs on which the operating systems Windows 7 and Windows 8 are installed. This became especially noticeable for owners of Nvidia 1000 series video cards, on which the hash rate decreased by up to 50%. The most correct solution in this situation is to install the latest version of Windows 10 instead of the already outdated 7 and 8 or go to LINUX: HiveOS, RaveOS. But if for some reason you do not want to do this, then the simplest solution is to switch to the latest version of NBMiner or Gminer, in which this problem for Windows 7 and 8 has already been solved. NBminer starting from version 36.1 and Gminer newer than version 2.38 will suit you.
