FPS drops back in pbe

FPS drops after maintenance
I can't record the game because of how low the fps are but after today's maintenance each game with swain/rengar has been droping fps like crazy. From 80-100 normally to around 10-30 during team fights and 35 when farming alone in lane.
FPS Drops are back again. I made a thread weeks ago, got fixed and I'm pretty sure it's the same problem again.
