Serious FPS Issues as of the recent patch. ( RIOTER RESPONSE NEEDED ASAP )

As of the recent patch, the game has been experiencing some serious stuttering and fps drops for many users including myself. The issue doesn't seem to be remedied or solved by mere windows optimizations or cheating our way around it. The issue is from the game itself as far as I've noticed.

I've uninstalled the game multiple times, it didn't help. I tried playing other games such as overwatch and total war warhammer 2. And that's to say these games are pretty heavy and require a decent amount of power to operate at ultra settings, luckily my pc just so happens to have high end specs.

Both games worked smoothly on ultra settings with a fixed 144 fps. I checked the cooling system, and the temperatures were perfectly stable and correct for my gpu, cpu, and even the monitor.

I filed a ticket to the player support about the issue thinking I was the only one with the problem, despite knowing that the issue is from the game itself and not me. I received a response suggesting the mere windows optimizations that I've already done and looked into myself.

Now I'm posting this here to raise awareness about the issue since I've noticed a decent amount of players across the regions posting about this issue. It is very serious for riot to pay attention to this issue since it is technically making the game unplayable/difficult to play for those affected by it. The issue is basically the fps not locking to the cap, it drops from 144 > 120 > 133 > 143 constantly through out the game specially after auto attacking or using your abilities. The trigger for this issue is when minions spawn, or after they spawn and that massively causes the game to stutter.

Hopefully, riot will look into this post and raise awareness about it to the HQ.

Thank you in advance riot.
