Hi! I have a Ryzen 1700+Vega 56 on a MSI x370 Carbon Pro Gaming, recently reformated with Windows 10 version 1809, latest mother drivers + Radeon 18.11.1

I have a strange problem. If I start Windows and run SRB right away I get 1850H/s. If I leave it alone for a couple of minutes (?) and then I start SRB, I get 1200H/s. I have to restart Windows or suspend/resume Windows to get 1850H/s again. I know that the suggestion is to have other radeon drivers but last week I had 18.5.1 and was having the same problem.

Is there a way to fix this? Or maybe restart the driver without the need of restarting Windows or suspending/resuming?
