So yeah, I want to discuss or point out why I think Valve needs to fix Anti-Cheat issues. They have VAC but apparently its doing jackshit, be it Counter Strike 2 (any previous iterations) or something like Hunt: Showdown the prevalence of cheating players is non deniable. For me personally it has come to a point that I am not enjoying playing those games anymore, although they are great games by itself. But the amount of occurrences being killed or playing against cheaters is at a height, where I don't see the point anymore.
- Why I think Valve is the only company able to something against cheaters?
Because they have the tools with VAC already aiming to prevent cheaters. Valve has got the resources to actually invest into something more profound which could be used for any game where anti-cheat protection needs to be implemented. And lastly Valve is the company which is interested in furthering the ability to gaming on Linux, the anti-cheat solution needs to work on both operating systems. Only Valve has the motivation and means to achieve that with their knowledge and resources. What do you guys think about the topic? Is the fight against cheaters hopeless? Do you think some other entity should provide anti-cheat protection, why? I skimmed over "anti cheat in linux kernel" posts in the net, but I have very little knowledge about the topic, what is your stance on it?
Edited: Mixed EAC with VAC. EAC seems to be part of Epic Company. Both of these tools seem unable to prevent cheating like mentioned above.
Sometimes, just for practical performance reasons, with realtime games, the client is gonna need access to data that would permit one to cheat. You can't do some game genres very well while keeping things on the server.
Consoles solve this by not letting you modify your computer. I think that if someone is set on playing a competitive game, that's probably the best route, as unenthusiastic as I am about closed systems. The console is just better-aimed at providing a level playing field. Same hardware, same performance, same input devices, can't modify the environment.
'Course, with single player games, all that goes out the window. If I want to modify the game however I want, I should be able to do so, as it doesn't hurt anyone else. I should be able to have macros or run an FPS in wireframe mode or whatever.
For PC competitive multiplayer, in theory, you could have some kind of trusted component for PCs (a "gaming card" or something) that has some memory and compute capability and stores the stuff that the host can't see. The host could put information that the untrusted code running on the host can't see on the card. It also lets anti-cheat code run on the card in a trusted environment with high-bandwidth and low-latency access to the host, so you can get, for example, mouse motion data at the host sampling rate for analysis. That'd be a partial solution.
Sure, it'd be a solution for five minutes until someone delids the secure enclave on the gaming card, extracts the keys, and builds their own open source hw alternative.
High-performance FPGAs are actually relatively cheap if you take apart broken elgato/bmd capture cards, just a pain in the butt to reball and solder them. But possibly the cheapest way to be able to emulate any chip you could want.
Not a problem. You can potentially go for an attack on hardware, maybe recover a key, but you have a unique key tied to it. Now the attacker has a key for a single trusted computer. He can't distribute it with an open-source FPGA design and have other users use that key, or it'll be obvious to the server that many users have the key. They blacklist the key.
It's because hardware is a pain to attack that consoles don't have the cheating issues that PCs do.
