Tried the latest v355.60 geforce windows 10 x64 drivers as well as v353.62, the previous version, to no avail

ShadowPlay just won't turn on. Could this be related to another service or something else. Thoughts appreciated, cheers

Hi Krohm,

According to the official System Requirements, the software is not supported on Windows Server 2016.

I suppose we could post related problems in the official forum for better help:

Or, contact the support for help:
