Been trying to figure out why Arma 3 seems to suddenly be performing a lot worse than before. 
Never noticed this before, but is it normal for the Core clocks to be going up and down like this during gaming?
It seems to be going between max and boost clock. Everything is on max performance.

Thank you

I've never overclocked the card (and don't intend to yet), so I pretty much just kept everything at default. I use afterburner just for monitoring mainly, and then a light fan curve
