Ooh and it's a giant yellow banner you probably won't miss, and not some two-shades-ligher-than-the-background nonsense.
Good job, Valve.
However, it's only being forced for kernel-level anti-cheat. If it's only client-side or server-side, it's optional, but Valve say "we generally think that any game that makes use of anti-cheat technology would benefit from letting players know".
I will always love Valve for their ability to use corpospeak against corpos.
Your game has anti-cheat?
Wonderful!
I'm sure that always only results in an improved experience for all gamers, lets let them all know!
=D
That’s awesome! GTA V just screwed everyone on Linux! What a rug pull.
Adding kernel malware after the fact should entitle every single owner who requests one to a full refund no matter how long has passed.
Full agree. I do want some kind of policy for games that introduce anti-cheat both during early access and after release. Bricking a game you paid for should offer some sort of recourse.
I'd really like Valve to take an official policy on post-release changes that break games, but for what it's worth they have not given me any hassle with refunds in these scenarios.
That’s exactly what Valve did. The automated refund system wasn’t available, but you could request a manual review and cite the added anti cheat; Valve was refunding those who did so.
Easy Anti Cheat - requires manual removal
Wait, so this sketchy, privacy-invading stuff remains even after a game is uninstalled?! I had no idea.
How is this stuff not classed as malware at this point?
Oh it was initially classed as insanely intrusive malware when kernel level AC was introduced about a decade ago, by anyone with a modicum of actual technical knowledge about computers.
Unfortunately, a whole lot of corpo shills ran propaganda explaining how actually its fine, don't worry, its actually the best way to stop cheaters!
Then the vast, vast majority of idiot gamers believed that, or threw their hands up and went oh well its the new norm, trying to fight it is futile and actually if you are against this that means you are some kind of paranoid privacy freak who hates other people having fun.
Do you remember when Sony released cds that when inserted into Windows computer auto ran an installer that installed a rootkit that made it impossible for Windows to see any processes or files that started with a certain sequence of characters instantly turning any malware that named its files or processes similarly powerful rootkit. Oh and it installed a cd driver that made it impossible to copy their music.
Suggested removal was a full reinstall of windows.
Any program having kernel level access is spyware. This is getting ridiculous.
Vanguard anticheat...
I feel like they're doing this because they are going so hard with steam deck. Regardless, good on Valve for doing this.
I wonder if you phrased it the way the Play store does: This game wants permission to:
etc.
Think anyone would install them?

Can someone explain like I’m stupid on kernel level anti cheat and why I should watch out for it? Not a dig at all, a genuine question!
To put it very simply, the 'kernel' has significant control over your OS as it essentially runs above everything else in terms of system privileges.
It can (but not always) run at startup, so this means if you install a game with kernel-level anticheat, the moment your system turns on, the game's publisher can have software running on your system that can restrict the installation of a particular driver, stop certain software from running, or, even insidiously spy on your system's activity if they wished to. (and reverse-engineering the code to figure out if they are spying on you is a felony because of DRM-related laws)
It basically means trusting every single game publisher with kernel-level anticheat in their games to have a full view into your system, and the ability to effectively control it, without any legal recourse or transparency, all to try (and usually fail) to stop cheating in games.
And it's worth noting that trusting the game developer isn't really enough. Far too many of them have been hacked, so who's to say it's always your favorite game developer behind the wheel?
Or, even better, when you let a whole bunch of devs have acces to the kernel...
... sometimes they just accidentally fuck up and push a bad update, unintentionally.
This is how CrowdStrike managed to Y2K an absurd number of enterprise computers fairly recently.
Its also why its ... you know, generally bad practice to have your kernel just open to fucking whoever instead of having it be locked down and rigorously tested.
Funnily enough, MSFT now appears to be shifting toward offering much less direct access to its kernel to 3rd party software devs.
More importantly, if traditional anticheat has a bug, your game dies. Oh no.
If kernel level anticheat has a bug, your computer blue screens (that's specifically what the blue screen is: a bug in the kernel, not just an ordinary bug that the system can recover from). Much worse. Sure hope that bug only crashes your computer when the game is running and not just whenever, because remember a kernel-level program can be running the moment your computer boots as above poster said
Making it super simple, it runs with full access on your machine, always. It can fuck anything up, and see everything. It can get your browser history, banking details or private messages you enter, activate your webcam or mic without you knowing, or brick your computer even.
And you can't even check what it's really doing on your computer because it's a crime under US law.
Finally, it can get hacked and other people than the creator can do all these to your computer as well,as it already happened once.
Easy, a bug in battle eye forced me to reinstall windows, this kernel access has to go.

Why is kernel-level anti-cheat even a thing?
If I was trying to prevent cheating, I'd hash the relevant game files, encrypt the values, and hard-code them into the executable. Then when the game is launched, calculated the hash of the existing files and compare to the saved values.
What is gained by running anti-cheat in kernel mode? I only play single-player games, so I assume I'm missing something.
Because there are kernel-level cheats
What you proposed can very easily be bypassed without even needing kernel access by just editing the executable code that checks hashes to always return true
Modern cheats for multiplayer games don't modify local files (or attribute values in memory), since the server validates everything anyway. They're about giving you information that's available but not shown in the game (like see-through walls, or exact skill ranges), or manipulate input (dodge enemy damage, easy combos). Those cheat can run in kernel mode (or at least evade detection from user mode), so the anti-cheat needs kernel mode to be more effective.
since the server validates everything anyway
Oh you sweet summer child.
The server doesn't validate shit, because that takes up CPU cycles on THEIR hardware, which costs them money. A huge part of kernel level anticheat is forcing YOU to pay the cost for anticheat, so they can squeeze a few more pennies out of it. And if your computer gets owned because they installed insecure, buggy malware on your system...? Well, they'll just deny. After all, it's kernel-level, how are YOU going to prove anything?
I bought Sea of Thieves about 5 years ago. Recently, they added kernal-level anticheat (which does precisely fuck-all to actually stop cheating). While that is annoying, I'm not particularly worried because the studio that makes that game is owned by Microsoft, and like all Microsoft products, it was banished to my windows partition with the rest of the spyware.
