Negative experience pre15

Can we get a rioter, a dev or literally anything to address this issue? I get it, okay? Windows 10, you hate it riot, is ok, is fine (even tho millions of pc's are running it right now) But seriously, the game is so negatively before the map changes that is actually insane, the lag & fps drops makes it unplayable. I literally get in games with this mindset: Okay, so before the gates open at 15 mins, i have small openings of 0 lag where my fps are above 100 and i can do a cool play to outplay my enemy or not miss that cannon minion. After 15 i play normally, but i lost too much early to be able to recover so i always resort to split-push since half of europe doesn't know how to deal with, but i almost never teamfight unless the game hits 42+ minutes because i literally can't.

After 15 mins if i won lane i play the game, if not i take resources to myself... & Splitpush alone

The point is: This inferno lag that needs to be fixed, it completely changes my playstyle negatively towards my team (personally i don't mind splitting and forcing my team to play a 4v5 - best case: 4v4 cuz i won lane)
