As title stated, the game is absolutely unplayable for me. I've been trying to play since new years and the game is still acting up, never going above 60 fps and constantly going up and down, causing even input lag as if it was actual ping. I really have no idea what to do to solve this. The game has always been running fine, but after taking a long break since the introduction of the new runes (sorry for the earlier typo) and coming back in january, it's been impossible to do anything on it.
Should have added these when i posted but i'm silly: Windows 10, 16 GB RAM, 1060 6GB, i7-6700
