Severe CS2 Hit Registration Glitches Ruin Competitive Gameplay

I have been experiencing severe hit registration issues in Counter-Strike 2 competitive mode for a long time. Even though I clearly shoot the enemy player first—especially with the AWP—it feels as if my shot never registered; I end up dying while the opponent stays standing despite taking a headshot. Blood even splatters on the enemy player when I hit them in the head, yet they still do not die, and then they shoot back and kill me.

There is no issue with my internet connection, as I use a very stable 1 Gbps connection. Because of this, I believe the problem stems from the game's hit registration or a server-side technical issue rather than my own connection.

I cannot enjoy a proper competitive experience in Counter-Strike 2 under these conditions. I want these hit registration and server-side issues investigated and fixed to provide a fair, balanced gaming experience that does not waste players' effort.
