Input lag in Rivals

I've got a huge input lag (~1-2 second) from a 4th second of the match. 

I can't move players, I can't pass, I can't do anything. Even pressing the "start" button takes a few seconds. Opening and closing the menu, however, returns everything to normal for a couple of seconds, but after 5-10 seconds, the game becomes unplayable again. Anticipating some trivial and somewhat stupid questions, I'll say that my internet connection is stable, with a speed of 50 MB/s. My computer configuration also has nothing to do with it, as the issue persists at all settings, from low to high, including rendering scaling to 50% of 1080p.

 And most importantly, there are hundreds, if not thousands of players with this problem.

 But beyond the claims that "we fixed everything in the new update," nothing has changed.

The FPS drop in the second half,  the input lag issue, and other issues are not the fault of the players, their computers, or the internet.

 It's the game and its developers' fault that they can't fix what a huge number of players have been talking about for months.
