VAC is an absurdly long, & awful joke of an excuse that calls itself an anti-cheat.
BattleEye is in my opinion, one of the best anti-cheater software's ever used in gaming.
Escape From Tarkov had only easy anti-cheat, hackers every 5/10 matches, now that BattleEye is here, you get 1 hacker every once in a blue moon, but mostly die from De-sync deaths. (Dying while behind a wall from shit ping/netcode/programming)
I've played with a dude that purchased hacks after years of getting his ass handed to him in competitive matchmaking. How can you expect to get better when you have to purchase skill?
