Cheats/hacks or unstable connection?

I just finished playing a few matches and I'm not sure what to make of it.

Some of the matches began with an unstable connection notifications. This just started happening since I switched to ethernet connection.

My players felt generally felt slow. On one occasion, I'm chasing the  RW with my LB and it felt like I was jogging the whole time despite holding down the R2 button. Also, my players had terrible ball control. I would tap "X" and the pass receiver is took 3 touches to gain control of the ball, often times running in the opposite direct. I R1 sprinted into the 18 yard box and my player inexplicably turned away from goal when I pressed shoot. Overall, it just didn't feel like I had much control over my players.

I've heard there are programs/software cheats available for PC. Can anyone confirm whether or not there is cheating going within the PlayStation version (I turned off cross play)?
