massive lags and crashes

Hello, since the start of the 3.27 league, I've been experiencing constant lag spikes. I've tried different servers, and they appear practically everywhere, even when hideouting. I've tried solving my problem through YouTube videos, but they haven't worked. When I do an encounter, like Ritual, or Alve, it immediately disconnects me to the game panel.

I didn't have these problems with 3.26, even when playing on higher settings. The only time I got kicked out was during Ritual.
