Okay so I have't played League in months but one of my friends told me to play again because URF was back. Of course I did and when I hopped into an URF match, I noticed my game froze really frequently. The freezes were mostly followed by the game alt tabbing out and back in. This has caused my game to crash multiple times, and by that I mean it froze and my only option was to force shutdown my computer. (Holding the power button down for ~4 seconds) I am reinstalling the game as I am typing this, so I don't yet know if it will fix anything. I just wanna hear some of you guys' opinions on this and maybe some tips.
