We were able to play rainbow six siege without any problems in the patch before the season that came with the new character. The uncertainty in the sounds with the new update. In the game, we encounter various problems such as lag, freezes. But the biggest thing we've come across and making the game unplayable is desynchronization. You might think of it as lag, but it's different. Although our ping values are close or equal, the screen that I see from the server side and the screen that the opposing player sees are different.
While I'm holding the door entrance, I die before the opposing player is seen through the door. But when I watch the death screen, the player appears from the door, comes in and shoots me.
