I realized my lag spikes and inconsistent gameplay are because of Steam..

I played through EA app and my game runs smooth as butter.. its a whole new game. When I play through Steam, its choppy and the input delay is very noticeable. I only have 10 hours of Trial on my EA account, and the game I own is through Steam... am I going to have to buy the game again in order to play the game? I cannot play on Steam anymore... its so bad. I own the game on another EA account I have as well, ultimate edition that I paid for... yet I still cannot play that either through my account.

Not really sure what to do.
