Controller still not working on online matches in pc?

Works perfectly in offline matches like squadbattles and moments etc, but only works for the first 15 in game minutes of a match and then the game visibly slows down, and my controller no longer works. So frustrating, what did i buy the game for if i cant play it? Ive researched this problem and many others have the same problem, but the difference is it was 5 months ago. Has EA still not fixed this? Limiting fps to 60 and turning on vsync doesnt work too.
