FPS Issue - GPU Problem?

[Crimvos]

So just recently I noticed Rocket League would properly run 144hz on my 144hz monitor for a few seconds, then it caps to 60 or so and looks awful. I thought it was only RL. Turns out this problem affects every game. 
I noticed it also takes affect to CODBO Cold War. If I alt tab out and back in, the game looks great for a few seconds and then caps again. I don't know how to fix this. I have an ASUS ROG GTX 1070. I downloaded the ASUS GPU overclock software and made slight changes which may be the culprit but even closing the software hasn't made a change... Any ideas? Any help is greatly appreciated as I am stuck.

Yes. I just changed it to off in the control panel but the problem persists.

I think so, I can open it and it pulls up stats and graphs.
