Lags after Win10 update

Hello. I updated my Windows 10 on 1709 version. I never had any major problems with LoL gameplay, but ever since I updated my Windows, the game lags very much. Not in the queue, not in the main menu, but when I get to the loading screen it starts lagging. I join game 2-3 minutes after everyone and I move very hard, i move like 10 seconds after the click (my fps and ping are fine). Does someone have same problems as me, and can someone help me about this? Thank you.
