Personally I have only had 1 or 2 games since the launch of Codmw where I suspected the person was hacking and I play only on PC. I have actually been called a hacker a few times even though I never cheat/hack.
The key difference with me though is that I don't play Cod Warzone and instead, only focus on regular multiplayer. The problem with WarZone is that it's Free to Play vs regular mode which is locked behind a owning the full game... So a game that's free is gonna have a ton more cheaters, specially since there's not much of a consequence if they get banned.
