I have been having problems after the update for ranked season 2 and previous.

Every new server I join at some point I get lag for a second and FPS drops as well. I have tried configs to fix this but all I got was a quicker loading screen.

And full screen is not really full screening because when I'm in-game it says I using windowed mode. I try to turn it off but it just puts windowed mode back.

Please help
