Nearly every competitive game game is going to be utilizing some form of anticheat like this, so single player games tend to not have this issue (drm is a separate conversation)
What's frustrating to me is that games will run the hyper invasive kernel level version of an anti cheat on Windows but will allow Linux plays, which has no such level of access. If we're trusting Linux players with no kernel level monitoring, why not windows players? Have cheater really not caught on that there's a lower bar on that platform? I hope they don't because I like being able to play competitive games with friends without having to reboot first.
I believe Valorant and Roblox have had devs/employees state that supporting Linux isn't worth it for the small proportion of the player base vs the increased cheat risk as well, although feel free to take that with a grain of salt
I suggest compartmentalization for games, for example a dedicated gaming machine. That way, anti-cheat doesn't have much to take over. You can connect it to guest wifi, so that it doesn't see the LAN either.
