Bug: Frame Rate Issues

Client Bug: Not exactly sure what is causing my frame rate issues. I use to get consistent 250+ fps in game, now I am capped at ~30 no matter what video settings I use. This only changes when I turn Vsync on, then my frames shoot up to 60, can't really explain this one, but playing with Vsync on, there is definitely noticeable latency between my clicks and my champions movement/response.

So as I said not really sure what is causing this. This has only happened since I updated to 6.22. It could also be the new nvidia driver update, but I doubt it, cause that was focused on the release of other pc games like Dishonored 2, COD etc. No mention of anything related to league.

I have done a few things to try to fix this. I have reinstalled league completely, reinstalled my graphics card driver, even read and tried solutions from http://boards.na.leagueoflegends.com/en/c/help-support/eEOXRQxG-extreme-fps-drop-after-patch-622?sort_type=recent such as using task manager and closing leagueclient.exe once in game. Lastly I also tried turning off the new game recording stuff by xbox in the new windows update.

Anyone else having this problem/have a solution?
