I have the same issue.
Game was working just fine until the 08/08/2019 patch.
Now, whenever I double kills or simple kill too near to an ennemy or when I respawn with an interface oppen then closed, my game is freezing for 2-3 secondes. Very frustating.
If I can get to the end of the game, the end game screen appear with unlabeled variables and leaderboard, then it freeze 2-3 seconds and I got disconnect from the Game.
So it's not just a little problem but a big issue that make the game unplayable whatsoever.
Cpu: pentium g4560
Installed on SDD.
I also tired with various settings and all of my drivers and Windows 10 are up-to-date.
Should I also write a ticket to the support or is it the same issue ?
