Input delay and Graphical hiccups

I have found that the new map has a LOT of input delay and some graphical delay especially during team fights.

Input Delay is - Press the button... nothing happens for quarter second or half second roughly This also affects skillshots if you try to do them quick, such as move mouse over an opponent, press skillshot, move mouse behind you to right click to move... Well because of input delay, it didn't mark that it happened to after your cursor was moved from where you wanted the skillshot to go

As far as graphical hiccups, often during team fights right as abilities begin flying the game begins to slow down and chug up. It makes it basically completely unplayable when something like this is happening.

As far as my PC specs go, I have a GTX760 and a 8350 octocore I used to be able to play LoL at max settings and still get 100 fps Now on new map, I have lowered everything to the lowest it goes and I am still getting these problems. I can only imagine how badly its running on someone with a weak computer.
