whenever i play a dm or when i warm up in the range i consistently hit headshots and can flick relatively well. But once i get into an actual game, i whiff a lot of my shots and miss out on very easy kills. idk what i’m doing wrong

I lose so many gunfights in this game compared to cs (LE rank, im silver rank in val). The main thing that is bothering me is the initial first bullet. It always seems like the game considers me as still moving even though I counter strafed...

I’m currently (slowly) climbing in competitive and i was wondering if refresh rates matter? I expect the players in high elo will have a 240hz monitor but I’m unsure if that is the standard. I currently play on a 144hz monitor.
