Honestly I think the fix for cheating in gaming is well beyond the purview of actual devs at this point, it's a demographic issue.

Selling cheats is so profitable now, especially for the big games, that the cheat developers are very motivated these days. It seems the only way to truly stop third party interference is to have a combination of draconian, system hijacking anti-cheat software and netcode designed from the get-go around being ironclad against interference first and optimized for good performance second, nobody who enjoys games really wants that shit either.

The real issue is too many low class scum who somehow managed to derive enjoyment from cheating in a videogame have enough money and time for games now. Also doesn't help that the micro transaction monetisation, battle pass unlock dribbling progression systems all over even provide a financial/time-saving incentive to cheat. If the demand dwindled the cheat makers wouldn't have so many resources to devote to ruining games. The least intrusive solution is region locking your games and making sure the immoral members of your domestic community are too busy trying to survive being ostracized to have disposable cash for a gaming rig, a cheat subscription and multiple copies of the same game.
