I have a funny issue, trying to get my head around for days. Running the Xdag miner on Win10 Pro with 1070's and that does it quite well. Strange thing is whenever I connect a Teamviewer session the hashrate jumps like 15% up. As long as I keep the session open it stays high, when I close it the hashrate drops back again.

Motherboard is Asrock H81 Pro BTC 2.0. Internal GPU on or off doesn't make a difference. Windows is on High Performance and all the GPU clocks and settings (Afterburner) remain unchanged whether I connect Teamviewer or not.

I see a lot of reports Teamviewer affects the hashrate (a little) in a negative way but this is the other way around. When running the Claymore ETH miner the hashrate stays about normal or slightly lower with Teamviewer open.

That makes me think the Xdag miner hashrate could be quite higher with the settings Teamviewer applies when it starts a session. Just don't know what settings it could be.

Anybody seen the same and has an idea which setting in Windows or Nvidia should be changed to keep the hashrate maximised, Teamviewer or not?
