I didn't played closed/open beta so I don't know if people had this same problem.
since the game launched I was having fps issues, in a seccond my fps goes from 100 to 5 and I don't know the reason, but from what I've searched it's because of the game optimization.
Riot said the game would be really well optimized but it seems like it's not... and what makes me more upset is that they're not doing anything to solve it.
for weeks I've read people complaining about the same problem I have, but I haven't seem anything from Riot team talking about a solution to it.
now they added Ranked mode, but why???????? most people can't even play your game.
Riot, fix your game pls.
