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.
Most anti-cheat software can't do much on the client side. Really all it can do is look around at it's environment where it's allowed to look and see what's going on.
Most Cheat Software will run on a higher privilege level than the game; whether that's as an "Administrative" user or as "root" or "SYSTEM" in a context where it's running as an important driver.
In any case, the only thing the Anti-Cheat can reliably do on the client side is watch. If it's cleverly designed enough, it will simply log snippets of events and ship them off for later analysis on a server side system. This will probably be a different server than the one you're playing on, and it won't be sending that data until after the match has ended properly.
Sometimes it might not even send data unless the AC server asks it to do so; which it might frequently do as a part of it's authorization granting routine. Even when it has the data there may not be immediate processing.
Others have also mentioned that visible action may be delayed for random time periods as well; in order to prevent players from catching on to what behaviors they need to avoid to get caught, or to prevent cheats from getting more sophisticated before deeper analysis could reveal a way to patch the flaw or check to ensure cheating isn't happening.
Since cheat software can often be privileged, it also has the luxury of lying to the server. So clever ways to ensure that a lying client will be caught will probably be implemented and responses checked to ensure they fit within some reasonable bounds of sanity.
