LoL used to run smoothly on my computer but suddenly I'm facing major FPS drops during fights. Game starts smooth at 60fps then drops at 1-10fps which makes it hard to play. I'm facing this even at lowest settings and lowest resolution with v-sync/ anti-aliasing on & off. My friends laptop that has lower specs than me but is running on Win7 doesn't face this problem. I would really appreciate the help if any.
