Hi guys, here is a screenshot of my League of Legends client:

As you can see, it's windowed instead of fullscreen, and the gameplay is totally lagged. I don't know what happened, I've been playing LoL for some weeks and everything was just fine till the day before yesterday. Could someone give me a hand, please?

I fixed it

1. open this file in notepad: (..)\League of legends\Config\game.cfg
2. change "Windowed=1" to "Windowed=0"
3. change "BorderlessWindow=0" to "BorderlessWindow=1"

Save and close. Thanks!

were can i find this file i am getting really annoyed a tthis
