Yep. DRM’d online stuff and VR mainstays (Beat Saber, primarily) are the two sets of games that are keeping me tethered to Windows at the moment. VR games can be played via a Windows VM with GPU passthrough but for DRM’d online games you don’t really have any other option, at least if you don’t want to get banned.
I also run a Windows VM for gaming. One thing to note is that some games have (robust!) VM detection checks on launch, so you can’t even run them in the first place. Valorant is one example.
What do you use for the VM? Last time I checked, I couldn't find any free/FOSS VM tooling that allows me to do GPU pass-through on a Linux Host to Windows Guest.
It seems like you haven't looked into it much since it's was feasible for last 7-8 years..
Linux hosts had GPU passthrough working well before commercial software had such options. Nowadays it's just work out-of-box with Virt-Manager that just run QEMU under KVM.
It's been working for years for 99.9% of games excluding some invasive anti-cheats that ban you for VMs, but there literally only a few games that have issue with virtualization.
I use Proxmox and GPU passthrough works just fine (via QEMU). Note that Nvidia GPUs have less issues with passthrough, at least last I checked. See this guide: https://pve.proxmox.com/wiki/PCI_Passthrough
But if you’re running a standard distro, there are guides for most them.
Last thing to note is that your motherboard can make the process easier if it has good IOMMU support. Basically, you want a MB that puts your PCI slot in a separate IOMMU group. You can find examples by searching for “(MB name) IOMMU groups”.
Do you mean the presence of anti-cheat software makes them anti-player? Because I’d disagree. It’s a lot of work and expense to combat cheats, but is very much appreciated by many players (when it works)
Or they could just not trust the clients, instead of throwing the problem over the wall. A lot of these games with fancy anti cheat protection the cheat tools basically just tell the server "spawn me a vehicle right here" and the server just does it. Garbage.
> A lot of these games with fancy anti cheat protection the cheat tools basically just tell the server "spawn me a vehicle right here" and the server just does it.
Citation needed. I'd be quite surprised if it were common for servers of professional games to trust the client in that sense (i.e. allowing it to decide game logic like what gets spawned where).
As far as I'm aware the most common types of multiplayer cheats are
* wall hacks, which you could probably prevent by not sending the client any information about objects that the player can't see, but that would require the server to calculate the line of sight for every player/object,
* and aim bots, which I don't think you could prevent at all on the server side since they don't rely on the bot having access to any information that the player isn't supposed to have. They just rely on the bot being better at aiming. I suppose if you did all rendering server side and only sent the rendered graphics to the client (i.e. streaming), that would make it harder for the bot because it'd now have to do image recognition to find the target, but that just makes it harder, not impossible. Plus, game streaming wasn't well received for a reason and anyway, I don't think that's what you had in mind when you talked about "not trusting the client".
Look up BF2. Cheat tools would just disable limits locally on ammo requests, vehicle requests, artillery strikes, and so on. Server didn't check anything. It had fancy anti-cheat tech. Which was bypassed by just writing and restoring executable memory changes faster than the anti cheat detected.
Things are certainly not always as professional as they appear to be.
Visibility test is definitely feasible against wallhacks, it's not that expensive.
Aimbot is an assist cheat, which technically does not violate the physical rules of the game, so you are right that it's more difficult to detect. One solution to detect this class of cheating is to record the player's movement, and rely on a combination of outlier scores and outlier movement behavior to detect abuse. It's not watertight, but neither are any of these client side anti-cheat detection schemes.
Wow, it’s awesome you’ve solved the entirety of multiplayer gaming. Here I was thinking anti-cheating measures was a complex topic but it’s great you’ve elucidated me.
"just" is (tongue in cheek) a forbidden word in HN. Next thing you might find yourself claiming is that Dropbox is a worthless idea because it's "just" FTP.
Btw tell me exactly how an aimbot that takes the visuals from the player's screen and tilts the player's cursor so (or not so) slightly towards identified moving targets, are to be avoided from the server. Modern cheating is already a hard-ass problem to solve, much more so if no client-level monitoring is desired.

The very same way that you'd do it on the client. If I run an aimbot on an nvidia jetson devkit, using HDMI in to get the screen image and USB emulation to send inputs, your anticheat has to do the same work regardless if it's on the client or the server.
I think that makes sense; but doing it on the client means that your computer has to do the work for you, thus distributing the load among all clients. Doing it on the server would mean that their machine has to do the work for all players.
If we complain about companies being too quick closing up their servers when games are not as successful as they hoped... imagine if those servers were x10 or more expensive, due to that kind of analysis for all players. Companies would be much quicker to pull the plug, I guess.
Dropbox is a worthless idea (long term) because it's not running on my own server. :')
And exactly. You cannot detect that with client-side anti-cheat nonsense either. Record on the HDMI and output a fake USB mouse, why not? Botting doesn't break the physical rules of the game, so you're right that it's hard to detect. One "solution" is to record player movement on the server and detect outliers in behavior and scores. Not perfect (and also very difficult), but just as unreliable as client-side anti cheat nonsense.
it's anti-player when it is security theatre, which in 95% of cases it is.
When I start a game and I see an Easy Anti-Cheat banner I think to myself "Great now I can be killed by an aimbot while simultaneously hosting a root-kit voluntarily."
Why do you think these systems are advertised like that, at the forefront of the game load? It's so that the developers create a false trust in the playerbase that they're doing their damnedest to prevent cheaters, when the reality is that they paid a small amount of cash to a third party to use a system that does a piss-poor job at everything aside from being a symbol of effort and adding incompatibilities where there shouldn't be.
eac bypassing is trivial to a laymen, that doesn't bode well as a defense against people that have made cheating their hobby.
and to be clear : I use EAC as the example because to me it symbolizes the 'security theatre' side of the effort. Real anti-cheat efforts exist, and those should be applauded. EAC ain't it, but it's the industry standard... worrisome.
I personally would far rather have the occasional cheater than have the game install literal rootkits. It's absolutely bonkers that people are willing to accept that.
There's nothing "esports" about wanting to avoid wallhacks/aimbots in games like Tarkov, Rust, or Destiny, which completely ruin the entire game for every player in the lobby in an instant. It has nothing to do with "esports" and everything to do with actually being able to play the game. Do you also think it's because of "esports" when you're forbidden from cheating at a game of chess in person? When my friend plays Rust and gets upset because a flying aimbot hacker raids his base, gets banned, and comes back 1 hour later (buying a hot key off some shady 3rd party site), is he thinking "Damn, esports is really ruining this game"? No. The players are expected to fundamentally abide by the same rules. That's what a game is.
Realistically these days with how expensive most of these games are to run and make, if you do not keep cheaters away it can tank the entire project, e.g. Cycle: The Frontier basically had to shut down because they couldn't keep cheaters at bay, in a system that heavily relies on player count to remain healthy and fun. Once the cheating gets bad enough, people stop playing the game, which leads to a death spiral: it starts with bad queue times, which leads to people playing other games, and that spiral further diminishes the playerbase beyond a point of no return. Cycle barely made it 12 months and the result was a multi-million dollar project getting flushed down the drain.
A kernel level invasion of privacy is required to stop flying players? That doesn't sound right to me. Not to mention that apparently it isn't working if your friend is witnessing it.
So players of those games are sacrificing privacy for no security at all by the sounds of it.
I am glad that Bungie is going with fog of war for Marathon. And heck, given the features Marathon is getting, maybe someday Destiny can have those nice things too. We'll see...
I assumed that cheating is way more widespread amongst multiplayer gamers? There is a lot less anonymity in esports and if you get caught and blacklisted.. well you just wasted thousands or tens of thousands of hours.
It's pretty hard to have fun when the server is full of cheaters.
> I assumed that cheating is way more widespread amongst multiplayer gamers?
I mean, hard to call cheating in a multiplayer game the same as cheating in a singleplayer game. The former ruins the experience of others, the latter just affects your own session. Hard to be against cheating in a singleplayer context.
I was thinking about casual and professional online gamers (yet somehow managed to leave out a word in comment...). Of course "cheating" in single player games isn't even a real thing
The Valorant community is incredibly in favor of the Vangard anti-cheat that loads as an early kernel mode driver, and the pro/pro-am Counter-Strike scene plays on FACEIT because they have a strong Kernel-based anticheat. VAC, and server-side VACnet just doesn't cut it.
The only thing incredible is how upset people are for pointing out that it’s hostile to tell someone the game they enjoy playing is garbage and is not worth playing because it has anticheat.
You are conflating ideas. I don’t think it will be a productive discussion to go down the road of anticheat systems and DRM. We can all have opinions that are different.
What is productive is calling out hostile behavior and comments that do nothing but hurt the ecosystem. I see these type of strong negative opinions in a lot of areas of the Linux community. “Oh you do X, that’s stupid you should not be using the product like that”
The best possible, most correct, most defensible, most world-improving advice to give for dealing with a user-hostile product or service, is to have the strength of will to reject it and live without it, and live the example to show that it's possible and you won't die.
Or at the very least, it is AT LEAST as defensible a stance as "The more pragmatic/adult approach is to give the bully whatever they want than to go without their product or service".
That philosophy is not remotely automatically more correct or more adult or nuanced or any of the self-serving words anyone typically uses to try to grant their idea more legitimacy than it deserves.
Calling the principled stance "hostile" is itself hostile.
You can phrase it in a way that sounds emotional and shortsighted and jeuvenile, and certainly there are many juveniles who are guilty of that.
Never the less, rejecting a bad deal is still fundamentally a reaction not an action, a defense not an offense.
The publisher promulgating a user-hostile deal is inarguably the offender, the initial hostile actor.
You can decide that the bad deal is tolerable for yourself, but that is entirely your weakness and does not make that policy smarter or more correct than that of those that decline.
I am not here debating DRM or anticheat. Simple pointing out that telling someone the game they play is garbage because it uses anticheat does nothing but hurts the Linux ecosystem.
You can come up with another essay but I don’t think it disproves what I am saying. Telling someone the game they play is garbage is not increasing the Linux user base. I am sure there will be a retort here, “we don’t want those kind of users or related software”.
> What is productive is calling out hostile behavior
Okay; anti-cheat is user-hostile.
> “Oh you do X, that’s stupid you should not be using the product like that”
Okay, the thing I want is to use a game that I paid for, play it on the machine I own, and run it without giving it any special privileges (certainly not modifying my kernel). I trust that you will support that and not be negative about the way I want to use it?
What are you even arguing? I am not here debating if drm/anticheat is good or bad.
I am saying it’s hostile to tell someone who wants to run software but cannot because of a limitation in the OS that it does not matter because it’s garbage anyway.
The players of the game are willing to put up with DRM and anticheat in order to get the game. By taking a hardline stance against these, the Linux community is being user-hostile.
They are not, but both are symptoms of a consumer-disrespecting mindset.
- DRM does not serve the consumer, but the producer.
- Anti-cheat only serves the consumer if it is well-designed. However, if someone is able to design a game (technically) well, anti-cheat is unnecessary. And if someone cannot design a game, their anti-cheat is often a disservice to the consumer.
I don't like either DRM or anti-cheat solutions, not because I am not willing to pay the producers, but because I have been burned too many times by dysfunctional solutions.
> Anti-cheat only serves the consumer if it is well-designed. However, if someone is able to design a game (technically) well, anti-cheat is unnecessary.
That silly "speed of light" thing? Just design better.
> However, if someone is able to design a game (technically) well, anti-cheat is unnecessary.
Nonsense. It's completely impossible to stop cheaters these days, but anti-cheat technology definitely raises the bar. It's only "unnecessary" if you're willing to accept a large number of cheaters.
Some anti-cheat stuff definitely goes to far but to dismiss the idea entirely is just naïve.
Well if cheating is going to make the game almost unplayable the outcome is pretty much the same as you deciding to never install it in the first place due to disliking anticheat systems. So I don't really see the problem.
Obviously, you haven't been in a position where you had to patch the anti-cheat solution yourself in order to play the game you paid for.
Well-designed games offer limited potential for cheaters by design. An anti-cheat software can help to eliminate the little potential that is left, but often games are designed without cheating in mind and some anti-cheat software is put in place to solve all the issues that were produced by the bad design.
I think that there are very few tasks in competitive multiplayer games that humans perform better than machines[1], I don't think your statement holds true unless you exclude a huge amount of game genres or you take all the fun out of them. (E.g. no FPSs or ..FPSs with no aiming?)
[1] Unless we're talking about captcha solving competitions, for now, maybe. :)
You're right in that, if your server rejects inputs that are too fast, too precise, too robotic to be human, bots will emulate the top-playing humans ever more closely.
But the question I want to ask is: Is that a problem?
If all the bots and cheaters are playing indistinguishable from high-level real humans, where's the harm?
Or, to quote Westworld: If you can't tell the difference, does it matter?
It varies by game. https://areweanticheatyet.com/ is an interesting resource for that because they also track announcements by developers about whether or not linux support is eventually planned.
For example: Halo Infinite works fine, but Destiny and Call of Duty don't.
