Horrible Micro stuttering and fps lag latest patch

I have never had such a disgusting game experience as the past few days, I thought it was a one off but apparently not, playing Xerath everytime I release q there is like a 0.5second jump in champions, minions, everything, it is disgusting. There is noticeable jittering in game, borderless/ full screen doesnt actually seem to work anymore? I switch them but it bugs out for a moment and still has me in full screen mode, it feels like I'm running multiple instances of the game and I'm playing on the last one in line, it is THAT laggy. Fortunately for me I was playing on a smurf account when I first experienced it but still, not very fun. Running i7-8700k 16gb ram and 1080ti, all latest drivers.

We're testing a new feature that gives the option to view discussion comments in chronological order. Some testers have pointed out situations in which they feel a linear view could be helpful, so we'd like see how you guys make use of it.
