Delaying problem how to solve ?

After the new Update has arrived Cf is not working good as before.In each room the game got stuck for 1-2 seconds and in the next moment an enemy appears and kill me.
But my Ping is 150-160 not more. The Ping of the Enemys are also normal.
Since Mutant Update I have this Problem.
I have another example for this problem:
When i hit enemies head the headshot symbol appears slowly after 2 seconds.
In fact this is a kind of delaying/deceleration/slowing down.

Do anybody know how i can solve this problem?
