Lowered FPS (especially during teamfights) since earlier today
Not sure what happened but I noticed a few other people in games and a on the boards have noticed the same drop in their FPS without actual ping lag. Just making a thread so that Riot has a better gauge on how many people it could be affecting.
edit: for reference, I already play on low-spec mode and have the client closed during games etc. but i'm still dropping to 02~07 FPS during fights.
