FPS dramatic drop since release of patch 7.1

Hi, is anyone else having troubles with fps drop since the release of patch 7? I used to have a constant fps of 60 which is kinda of okay, but now my fps doesn't go over 11. I have read many similar complaints on the board and most players have said that it seems to be a bug since the game worked pretty fine before the release to the patch. P.S. I have updated Drivers, Cleared registers, reinstalled the game, checked for malware, turned off background software, done the hard disc fragmentation and even considered praying. I confess I am very annoyed with riot, I haven't played properly in months, we are being ignored. I would appreciate if anyone helped me sorting this out. Kind regards, Happollion.
