(In-game Bug) Slow down, 3x slower animations, sfx, and 3x longer cooldown timers.

After the latest patch in-game has been brought to an unplayable level. All the models do there animation 3 times slower. Example, auto attack animations are very slower, but very frequent with no time between attacks. SFX from abilities are so slow you could count the bullets on Miss Fortune's Make it rain ability. Abilities go on cooldown 3 times longer. the timer will say 4 seconds on Trundle's Chomp, but will take 12 seconds to be able to for me to use again (the time on the counter counts down very slow). I have tried reinstalling (did not restart computer). Changing settings on everything in game. Closing client and restarting client. I really don't know what to do, but I lost a team a game because I was unable to do much in teamfights and could only really push lanes. Ao if anyone could hope it would be most appreciated.

I can add photos of a champions ability going on cooldown and you can see how long it takes for it to be useable, but i rahter you just take my word for it.
