EDIT: We have at least one user claiming that EAC and BattlEye can NOT see what programs are running on your computer via proton on Linux.
EDIT 2: According to brucethemoose@lemmy.world with comment https://lemmy.world/comment/24738141
"Yes and no.
If you run task manager or something in Proton? It just shows Proton processes:
ImagePlaceholderBut all linux process, and tons of information about them, are readable in the /proc directory. They’re just files, accessible to the program.
Try
ls /procyourself.There’s nothing stopping anti cheat from checking that, if it’s configured to do it.
Which is pretty dang convincing to me.
If I have a good understanding, the Symlinks that Proton uses allow the games to view nearly your entire drive and see what software is running? Because Proton is explicitly NOT a virtual machine and merely a translation layer for Windows applications to run on Linux?
The reason I like to ask is because this is the general consensus, that Proton applications are not secure, but when searching online it doesn’t explicitly state anywhere if the games with EAC or BattlEye are capable of spying on Linux users. So I’m looking for confirmation on this.
Supported kernel level anti-cheat (EAC and Battleye) are not actually kernel level under proton on Linux. They run only in userspace, which makes them less “effective” than on Windows. However, you said yourself that wine are proton are not designed to be secure, and while I’m far from a professional who can point to anything specific, I’m sure that there’s still plenty of non-kernel-level info that they’re able to suck up and send back.
Yeah! Exactly! I just wish somebody could tell us more concretely what information they’re capable of gathering.
