Anti-cheat is actually a pretty interesting application of machine learning and I think it will be pretty successful at weeding out hackers. Only concern is false positives.
Crossplay on xbox is forced. Disabling it at the system level doesn't prevent PC crossplay. It only prevents what it calls "cross-network play" with other services (PC players can use xbox services). This is why the xbox setting is under privacy. It's just to prevent your xbox data and chat being shared with other networks and not to prevent you from playing against other devices.
The main developers of Ricochet anticheat are secretly running their own separate company on the side that sells the fucking cheats online for $50+ a month. That's how cynical I've become. MW2019 is that last Activision game for me, never supporting them again. Once a new COD title is out, last year's game is abandoned to bug/hackers/cheaters.
the issue with that is that you'll only be matched with people that also turn it off, which can often increase queue times by a lot, maybe even make it near impossible in some modes to get a full lobby going.
"We want to catch and remove cheaters within one hour of them being in their first match."
September's Black Ops 6 beta was apparently an important step in Ricochet getting its foothold in the new game. During the first weekend of the beta, detected cheaters were able to play an average of 10 matches before being removed. The second weekend was a lot faster.
"After tweaking our systems and deploying new detection methods for Weekend Two, we cut that time in half to five matches," the report reads. "That timing achieved our Time to Action goal. In fact, 25% of all Weekend Two bans happened during the first match a cheater ever played."
In total, 12,000 accounts were banned during the beta.
