I'm noticing a huge fps drop every 2 min in every single game since this morning. It even happens when I'm spectating a game. Every 2 minutes I'm in the game client, my game will freeze for a second. So in game, 2:00, 4;00, 6:00, etc my game will freeze. And as for spectator mode, it happens after two minutes when you start spectating ex: you start spectating at 4:27 and it will freeze at 6:27, 8:27, and so on.
I already repaired my client and the issue isn't solved. Someone in my last game was having the exact same problem as well.
Not sure what is the cause of the problem tho.
