Sadly, I don't have friends to play this with, so I've been doing solo queue.
I use this monitor from many years ago: https://www.amazon.com/ViewSonic-VX2370SMH-LED-1080p-Frameless-Monitor/dp/B008RM235I?th=1
For the setup I have a mouse and keyboard, but I've been using a PlayStation 5 controller since I started playing. I felt like I was too stupid to grasp playing with the mouse and keyboard.
The sensitivity has been set around 90. in-game.
The PC itself has a RTX 3060 Ti, i7700k, 16GB RAM, and a 1TB SSD.
