Weird nvidia driver issue 398.86 and 399.07. When I install 399.07 I get powermixer and no gsync

When I install 398.86 I get gsync.


Edit: I could be wrong it may have not been called powermixer but it was something power I believe. Trying to find a screenshot.

Just know for sure 100% Gsync wasn't there at all.

This is not a laptop.
