Windows 10 update did it, it increased how much memory it needs, so is not related by the dag file, is related by how much memory windows 10 is allocating to be in use. Windows server still okay. I guess soon miners with 3gb gpu will ditch windows 10 and will start using windows server or older versions of windows 10. 1511v works without any problem, problem falls only on fall creators 1709v and after it i guess.
Also I already mentioned this 4 times before it happened, you trolls never listen to me anyway.
It must be related to this "Addresses issue where, in certain hardware configurations, the frame rates of DirectX Games were unintentionally limited to a factor of the display's vertical synchronization."
So it means that by increasing the GDDR memory allocation, fixed the issue.
