EAC on Steam Deck / Proton / Linux

Just a click of a button away, BHVR. What would you have to lose by increasing the amount of players who can play your game?

This game is the last reason why I keep a windows install, all my other games I can play either natively or with Proton :/

I can confirm that after last update released today, the game doesn't start anymore.

But instead of Pyc, I get the EAC logo and then the game closes itself, the unreal crash report window showed for a bit lol.

I'm waiting for DbD on Linux since long time. I hope to have it by the end of this year. :)

and who is him? He isn't in the BHVR team, so he doesn't know nothing like us lol. Why would you trust a random person who says a date?

Don’t expect this patch to work either. I checked the wine64 binary for EAC and it still doesn’t exist, so it still hasn’t been enabled server side.

I get the exact same result as last patch. Loads all the way to the first loading screen, then crashes when Initializing EAC.

+1+1+1+1+1+1+1+1

I wish Valve would name and shame Devs not supporting steamdeck, maybe the public embarrassment would light a fire under their ass.

Don’t worry, considering the latest stats for how many more Steam Decks are out there compared to last month, gamers will do that themselves. In about 6 months time, if you don’t support Deck, you’ll be mostly a pariah

after today bugfix i new error:

"in order to access this content, a network connection is requried. Provider ID: Press here to display your Provider ID"

IMHO, the fact is: enabling Steam Deck and Linux support aren't a priority for them.

That's because this will not bring new sales. Who owns a Steam Deck is (most of the time) someone that already own the game on Steam, probably with all the DLC and stuff. The Nintendo Switch is a proprietary solution and bringing the game there, for example, equal to new sales.

This doesn't mean that it will not be enabled in future, but is not a priority actually for the devs.

This is just my idea about it, I can also be wrong. I also hope that It will be implemented soon, but i don't think so.

I don't play anymore, but my gf did, and this game Is the only reason stopping me from removing Windows and install Linux actually.

Cheers.

pleasee..

of course, native builds better than emulator, but we talk about steam games. all "native" builds = it's win build under emulator (dx to gl translator, etc). i doesn't see difference in performance in native game build or emulator. proton is easy way to support linux, instead building some native version

Wine Is Not an Emulator... but not native :) via wine/proton u run win build. proton cant get performance as in win, but can get some bugs

Bhvr this coulda been you but u playin

(The Steam/PC version of P5 here is played on a Steam Deck in case it's hard to see)

I am not sure how much truth there is to the "rumours" but apparently the reason for said hesitation is the fact that they haven't been updating EAC for quite some time, which is why it takes a while to "catch up" since updates are implemented gradually. In other words, you need the latest EAC version to support Linux.

But again, that this is something that I read on the forums, and I have no clue whether it's actually true or not, so take this with a grain of salt.

AFAIK they wouldn't need to redistribute the game. The files for Proton support are already in the game's EAC folder. BHVR just hasn't enabled compatibility on the EAC developer page.

Let’s be totally honest here. It’s not like they would update their anticheat to support linux when they can’t even update their anticheat to block blatant cheating from the game. Have you seen content creators lately? Everyone’s harassed by cheaters and I don’t even start with the IP leak problems.

Note that in order to prevent actual cheating, EAC is just a band aid, not more. It's like putting steel bars on your door to prevent burglars from intruding your home, but leaving the windows untouched.

EAC has no notion or idea what cheating means in DBDs context. Remember that EAC is used to "protect" all sort of games. The thing which EAC does is trying to prevent other applications to access DBDs process space and modifying variables. It probably also has some sort of integrity protection which tries to detect when the DBDs executables (or itself) are modified.

However, it does not check whether some survivor's DBD client reports "Hey, I've hooked a survivor, although I am not even the killer". That has to be done by behavior on their servers.

Theoretically, one does not even need to modify the DBD executables when one reverse engineers how the communication between the server and client works. With this method, nobody needs to crack EAC at all.

Worst of all, EAC is guaranteed to be able to be circumvented. Since it only runs on your computer, over which you have the full control over, it is possible to patch all integrity checks (and all checks for that matter) of EAC completely out and do whatever you want. Of course this is not easy, but it is possible. From behaviors point of view, any player's computer should not be trusted - that's crucial! However, in the current state of the game, the server seems to simply believe everything the client tells them, which is really sad. Some things are easy for the server to check, e.g. the aforementioned "a survivor hooks a killer". Wallhacks in contrast, are essentially impossible to detect server-side, since all the player's positions has to be made known to all players at some point. But many flashy things we are seeing in DBD's cheating scene right now should not be possible if there are any checks in place (on the server!) at all.

Checking on behaviors servers has the advantage that the servers are fully controlled by behavior. Anything the server prevents from being done cannot be done. Proper checking on the server is the key to prevent most of cheating - and it's the only way. Anything on the player's computer can be bypassed in some way - not on the server (unless the server itself gets hacked).

So, updating EAC is nice, but will not help at all against this massive influx of cheating. Because for this to change, behavior has to work on this part of their code. EAC doesn't help at all with this.

Oh ######### so basically their servers don’t check at all if people catch packets and modify and send modified packets back? Oh damn that’s not great at all. No wonder stuff is going all over.

+1, Dead By Daylight for linux

i've quitted dbd because of this.

So tired of using virtual machines to play lol

Just got my 1 year anniversary badge on this forum account. I created this account the same month this thread was created.

Made an account just to complain about this. I unfortunately bought the game before checking for proton compatibility, and it's too late to refund now - please, add eac support for linux! It's such an easy thing to do (Yes I understand checking the box will lead to some issues on our end, but can't you let us figure that out for ourselves?) I will not be supporting any future games until this is resolved.
