In the case of VRchat, it might be a good solution, but look at their model - it wouldn't work. Quoting: scaineServer side AC isn't a silver bullet to every problem. They're not 'lazy' or 'incompetent' just because cheaters are assholes. They're just trying to earn their living like everyone else. This situation is because cheaters are dicks. I think Faceit and Fair.fight (I think?) are the only two vaguely viable solutions out there AND THEY STILL RELY ON CLIENT SIDE PROTECTIONS! The Fairfight, I seem to remember needed kernel/rootkit client side protections, I think. Honestly, SS-AC usually introduces so much lag/latency that it's rarely a good solution. Nope, you move everything client side and if you're successful, then you can cross/burn those bridges when you come to them. There's uncertainty and success is the biggest uncertainty of all, so you're not buying a massive server cluster (or paying for an elastic version in a cloud instance) for a free game in the earnest hope it does well and you can sell skins. It's easy to see its success in hindsight and say 'lazy devs, should have used server side', but that's not how a business model works. Remember that SS-AC is computationally very expensive, because everything happens on the server (duh!) and now remember that VRchat is a free game. Server side AC isn't a silver bullet to every problem. As they said in their blog post announcement: Since Easy Anti-Cheat supports Linux, the developers ensured and tested it working for Proton and Steam Deck so there should be no issues continuing to run it. The developer said addressing those concerns is their 'highest priority' and they're moving around their roadmap for it. The downside is that some big features that a lot of people enjoyed have been lost, since no modified clients can be run, and some people can't play at all due to it. Plus, they explained that every month 'thousands' of people have their accounts stolen due to these modified clients. They allowed users to 'attack and harass others' which caused endless moderation problems. Why does such a social space need anti-cheat though? As they said in their announcement modified clients became a big problem. Recently though, they added in Easy Anti-Cheat and the community is currently very unhappy with it. Despite the name, VRChat is not a VR-only space and it's incredibly popular.
