Suddenly Lagging after patch

I'm getting regular fps but occasional extremely annoying freezes, like a screen freeze for half a second now and then. 

Was working perfectly fine before the patch, I wonder what they did wrong ;(

Edit; 

By the way I was wondering if it was just me with this issue so I asked in post/pre-game chat and apparently quite a few people are experiencing the same issue. Had like 4-5 people answer "yes, same issue" when asking once!
