Rule number 1 in performances debug :

It's always I/O.

If it's not IO, then the code should be REALLY bad.

Playing Battle Royal with friends, had to leave 2 of 4 teammates behind as the play area was shrinking and they couldn't be rescued. The 4th player ran me over with a game car just to get revenge for our other team mates.

With me alive we actually had a fighting chance to win the round. (8 kill streak and lots of ammo with a decent tactical position) ....but NOoo the fucker thought it more sweet to kill me rather than help me win the round!

Fuck this shit, I'm out!
