I had huge fps drops so I contacted riot support and after few messeges they told me to use pingplotter to see if thats the issue. It turned out that i have 100% packet loss to their servers. I've tried with my mobile hotspot and the result is the same. So now i dont know if the issue is on the side of my ISP or mine.
