Game not running "fluid" after patch 8.6 with fps drops

I have a pretty good computer, I can run all releases usually on ultra with no trouble but lately I've notice that my game is kinda lagging FPS wise and I have no idea what might have caused it, the only thing I know is that since patch 8.6 it's been worse, my game freezes when I swap the tabs on the shop, when I change ANY kinda of graphics settings my game freezes for almost a minute. Also when the game is over it freezes and then teleports to the victory/defeat screen. Anyone has had it before? Any tips of how to solve it?
