I'm getting this too in H2H and house rules. Weird thing is it seems to get exponentially worse as the game goes on. First play is not too bad, second has like 5 seconds of lag between button press and it actually happening on screen. By the third play I can't even select a play as I get a penalty before it registers. Then I just have to quit out.
Doesn't appear to be performance related, I get 60fps the whole time, CPU sitting around 75%. My internet is 200mbp/20mbps. In offline it's ok lag wise however the gameplay does slow down at times (again FPS is 60fps though).
Me to unplayable keep thinking people are cheating becouse lags so bad
