Update: Turns out, this is true. As a Valve developer did reply to a user on the VKx Discord to say "they're probably referring to the ongoing conversation, which is currently stalled by the NDA, yes" which I've now seen myself—thanks for the tip, MartinPL.

Update #2: On Feb 25th Easy Anti-Cheat did finally email back to say "Thank you for contacting us! Our apologies for the delayed response. We are in a process of working with Valve to bring the support for Steam Play. However, there is currently no ETA for this."

Original article

Treat this with a pinch of salt since we've been unable to confirm it, Valve and Easy Anti-Cheat are apparently working to get it supported with Steam Play.

I've held off on writing about this, as I have tried to reach the EAC team multiple times and I've also tried speaking to Valve. Neither have replied to me, sadly, but the people over at EAC did reply to one user on Reddit to say this:

Thanks for reaching out!

While Easy Anti-Cheat already supports native Linux games, unfortunately it is not compatible with the Steam Play emulation yet. We are currently working with Valve to bring the support for Steam Play as well. However, at this time we cannot promise a release date.

Our apologies for the inconvenience. Despite the troubles, hope you have a great day!

I'm not entirely sure why neither party decided to reply to my questions on this, it could be that they were trying to keep it hush-hush until they had something to show for it.

It is quite exciting if true though, as getting EAC working in Wine/Steam Play would be massive, as it's the only thing currently holding back multiple titles from working well when played on Linux. With that in mind, it wouldn't be the least bit surprising if they are working on it given how it's going to be essential considering how many multiplayer games use it.

Valve/EAC, if you're reading this don't be afraid to reach out, I don't bite.

CestarianEAC already has (optional) wine support in, and the devs of Paladin were asked by someone to activate it so that people could play it again. They obliged and now paladin (a game that was unplayable due to EAC last year) is now playable.
Actually, it was only playable for a short time. I tested again only today, still the same, kicks you out 100% of the time.

Yeah I heard about that. I think it may have had something to do with a recent update to the game.

I don't do online multiplayer so this doesn't affect me directly, but it does show again that Valve is serious about Linux support and Steam Play. Good to hear.

I hope they don't give up on this, since EAC is developed by a company owned by Epic, and for then would be better to "not help the competitor".

Unless they're actually planing something with linux too, who knows...

I think its simple, the only thing they discuss is how much Valve have to pay to get EAC enabled with Proton.

Best Linux gaming news since they announced Steam Play with DXVK.
We are witnessing the future of Linux gaming being written.

Very glad that Valve created the SteamOS years back, this chain of events lead to Linux having a Steam client and all other things.

This can explain the lack of PROTON updates.....
Two months since the last one... That is a lot of time!

I wonder why Valve is putting so much effort into supporting Linux. My theory is that, currently, Valve and Microsoft are in direct competition, since Microsoft also develops games and I guess they even have a digital storefront. They could really use their ownership of the primary platform to make things difficult for Valve, and really other developers like Epic.

So, to have Linux support seems like having an alternative in your back pocket, preventing Microsoft from overreach.

Just a theory.

TermyI'm kind of baffled that Epic is allowing collaboration with Valve ^^
Glad to hear this though

I think Epic holding Valve back would be bad pr for them. They are already disliked for their anti consumer practices. If they work against Valve they will, hopefully, get much more backlash from PC community.
Valve could, and rightfully so, rub salt into wound that is Epic Store by pointing out how the company has ported Fortnite for so many platforms but neglected Linux, and now they are even stopping progress to make games available for the platform.
It would be disgusting if that actually happens.
