its weird a steamdeck user was able to get the game running while on my setup it just sticks to saying running but nothing ever appears, im on a rx 6700, cachyos so my chances of it running would be similar to a steamdeck but that doesnt seem the case

I got it running on my Deck also. Proton Experimental. First time I tried Proton Experimental it opened the game but froze. I force closed it and tried again and it opened. Doesn't recognize the buttons/sticks so I had to use the touchpad in the menues. Closed it after that. On my desktop (Arch, Nvidia) I can't even get the launcher to open let alone the game. The launcher window just opens and closes.

The game works on Steam Deck completely fine, however it doesn't start at all on any linux distro, the logs show minimal differences.
With Proton GE 7.55 you can get quite close to the log on Steam Deck but it still fails to launch the game.

steam-2709440SteamDeck.zip

EDIT: I have tested multiple Proton versions which all result in the same outputs in the log and closing after launcher. Even tried to copy the steam deck prefix to no avail.

i think the anti cheat is blocking the launch of the game, hopefully they will support linux some day.

with the latest experimental

when i click play the launcher will show running but the game will not start.
here is the steamlog

Really wired "AntiCheat" which discriminates Desktop Penguins :(
also in all other games form their brand seams to be a workaround with Hoyo/Collapse which is an alternative FOSS launcher. According to some statements (also readable on reddit) accepted by the Devs o.o

+1 here, unable to start it on Proton 8, 9 or experimental. The launcher opens but after clicking launch it will simply get closed without any message.

Haven't tested in Steamdeck because I want to play this in PC. Voted on discord for it

It's Linux Mint 22 - Kernel 6.8.0

Since it seems to run on Steam Deck, could anyone try using the Steam Deck environment variable? Maybe they added a special code path for Deck?

i have no access yet but i tried dungeon born and the splitgate 2 alpha which have the same "anti cheat" and the same problem (also only runs on the deck).

i tired SteamDeck=1 %command% with no success :/

Also tested SteamDeck=1 gamescope -W 1920 -H 1080 -r 60 -- %command% with the Delta Force Alpha

as many said only the launcher works the game crashes instant.

The only protondb report that says they got it working on Deck mentions Switch to older version: 7.0-6

you can see more examples from playable games: https://areweanticheatyet.com/?search=Anti-Cheat+Expert&sortOrder=&sortBy=

Dungeonborn for example (:

they all share "Anti-Cheat" "Expert" and all i checked run on the deck (fyi with terrible performance) bur not on Desktops.

All run fin on linux when you use hoyo other launchers based on hoyo (which as far as i understand simply don't load the expert anti cheat but are approved by the devs according to redit)

Wanted to create a new issue for Delta Force (2507950) but later I found out there is this one.
Game has separate app ID right now during alpha tests I guess.
This issue could be renamed IMO to:

Delta Force (2507950) / Delta Force Alpha Test (2709440)

So it could be found from https://www.protondb.com/app/2507950 by 'GitHub Issue Search' button.

System Information

Linux / Arch / kernel 6.10.7 / KDE / Wayland / NVIDIA 560.35.03 / Proton Experimental [bleeding-edge]

Symptoms

Launcher

• mostly works, I could "log in" (it uses Steam account, but you have to select region/country), change some basic launcher settings
• there is no music (not sure if there should be)
• tray icon kinda works, although the right-click menu won't ever close (there is just one option there anyway - Exit)
• sometimes the launcher will launch, hang, and crash
• with PROTON_LOG=1 it hangs and log gets quickly to a gigabyte, here's first 1024 lines of it: 1.log
• with WINEDEBUG=-unwind added (or without logging at all) launcher often freezes with this error, also see the log until this happened: 2.log

• here's a log (with WINEDEBUG=-unwind), where the above error didn't happen and I clicked LAUNCH button - after clicking it the launcher disappeared, presumably game tried to launch, launcher reappeared and it just crashed, log: 3.log

Actual game

Did not launch.
Sometimes I got launcher to say 'RUNNING' but no window appeared.

Weapon / Ammo Management Help Please
Hi Guys,

I'm a old guy that has a super newbie question. When preparing my load out for a mission, I always get a message that says "Your Ammo is low". This is after I went to my stash, double clicked on 10 boxes of 5.56 ammo from my stash and 6 boxes of 9mm ammo, When I double click on the ammo, it adds them to my load out in the Slots section and sometimes to the Chest Rig section.. Sometimes it shows them only 1 box to a slot, sometimes it stack them and shows a number over that square like 10. Finally I drag a box on top of my rifle and it changes to say 1/17. When I get in game, I have 1 round in the rifle. When I hit R to reload, it says I have no ammo.

I know I'm doing something wrong.

Any help is appreciated.

Tejay

still an issue here
steam-2951290.log

can someone maybe test on HoloISO and/or ChimeraOS ?

i got a friends PC specially for this event but i forgot it had an ** nvidia card :(
so no gamescope and no test :( only black screens.

If someone can figure out how to bypass the launcher then we might be able to actually launch the game .exe hmm

when launching with deltaforceclient.exe it simply launches and stops after a couple of seconds

here is that log

then here is the launcher log

They are supposedly "cross platform", I don't understand how they are not supporting Linux

They are supposedly "cross platform", I don't understand how they are not supporting Linux

If that was the case then they should be supporting Mac os but you don't see that happening either

Cross platform just means console and PC(windows)

They should be supporting the switch also but we don't see that either most likely because of its rather low end hardware

I'm wondering if this is an anticheat problem or simply a wine/proton issue when trying to launch the game

apparently they "consider" linux: https://www.reddit.com/r/pcgaming/comments/1er6s48/comment/li1m5yq/
i guess it is really on thier list since if you combine all the feature request / suggestion upvotes in thier discord linux is among the top.

but i wont get my hopes up. i would rather bet on the alternative hoyo launchers ^^ (which cant use anti cheat - no argument what so ever xD)

For reference, these apps apply here:

• Delta Force (2507950)
• Delta Force Alpha Test (2709440)
• Delta Force Demo (2951290)

Some people are claiming to run it on this Next Fest demo but I haven't seen any evidence of it

Still no luck running with any version of Proton (Experimental or GE builds).

Can get the launcher but immediately closes when attempting game launch. (Fedora 40 - Gnome - Wayland - Nvidia)

Anyone able to test with holoiso and or chimera os?
sadly i could not get them to work on a 1050ti and on my mainpc i could not get them to boot from usb :(

We aren't even sure if this is an issue with their anti-cheat or something else?

i dont know but according to this issue and proton db / reddit there are folks who say it runs on the deck but not any other linux distro.
So on nobara discord it was suggested to test with holoiso & chimeraos to see if it runs there. And maybe see if we can "fix" other distros.
but i dont own a deck and as written above i cant get both distros to run on my test / main hardware to do the testing myself :(

Indeed, there's a recent report saying that it works on Deck https://www.protondb.com/app/2507950?device=steamDeck

Tested it right now on my deck (LCD) and the game boots. Doesn't seem to have controller support though so haven't played a actual match except for tactical turmoil which seems to work at a decent FPS :)

I have no experience debugging these kinds of issues but perhaps a good approach would be to compare the Proton logs of someone who successfully launched the game on Deck with someone who failed to launch the game on Linux desktop to see what differs and fails

I have been told its to do with the non oled steam deck being manually approved for use in the game. so i assume it could possibly be a means of just spoofing the detection

That sounds like they're intentionally whitelisting devices? So they're not supporting Linux intentionally?

Yep seems like it, I was thinking of some Dev could figure out spoofing that we are all steamdeck LCDs 😂

Not cool tho that they are manually doing this, very interesting and wonder what the reason is as steamdeck has a desktop mode so it's not very different from Linux desktop and it uses the same proton as everyone else

I have been trying several things to emulate the Steam Deck when running the game:

• Running it through gamescope:

gamescope -w 1280 -h 800 -f -- %command%

• Running the Deck version of Steam:
  • Change .steam/package/beta's contents to steampal_stable_9a24a2bf68596b860cb6710d9ea307a76c29a04d
  • Open Steam with the command steam -gamepadui

The only noticeable change in both of these methods is that instead of crashing the game it says RUNNING..., but nothing actually opens.

In any case the demo ends tomorrow... Maybe something will change once the game actually releases in early access.

Hello, I tried with a few different versions of Proton. Experiment, 9, GE 9, and 7.06. I get login failed a few times, but after the second try it lets me in. The game never seems to launch though. The log file PROTON_LOG=1 is massive 2.1gb. I truncated it down because it just repeats the same call stack over and over.

Only steam deck

Steam deck oled can run without any problems

Steam deck oled can run without any problems

I don't like when studios exclude Linux desktop when steamdeck is literally a x86 PC and can do the same thing as a Linux desktop PC

The mods on the discord say linux is not supported not even on the steamdeck but the game works without issues on steamdeck, quite odd if they didnt actually intend on supporting the steamdeck

If so wonder what is causing this game not to launch properly and it would be awesome if valves engineers could chime in here if they know why linux desktop wont work with this game but steamdeck will

sadly i have no system where i can test chimeraos or holoiso
if someone can get this tested on those os would be really nice since they try to "simulate" steamos in a way (:

Is there a way to spoof it running on Steam deck?

https://github.com/ValveSoftware/Proton/issues/7964#issuecomment-2323181169
afaik only the SteamDeck=1 option.
I read somewhere about a protonhide but i dont see a sense it that.
so far nobody figured out the diffrence.

i tried to get HoloISO and ChimeraOS running last beta but sadly where unsuccessful in getting them to run on my testrig.
If someone can test those OS on a spare Drive or Partition it would be interesting to see if the game works there since they try to "mimic" SteamOS

Tried SteamDeck=1 %command% crash after pressing launch

Just to be clear, it only runs on LCD Steam Decks (I have played about 2 hours on my Steam Deck). Does not run on the OLED Steam Decks (brother and friend can't play this game on the Steam Deck). It's the same thing that happens with Metal Slug Awakening (I have over 200 hours on the Steam Deck) which is from the same publisher TiMi Studio Group.

I have Steam OS 3.6.20. I have the 256mb version. My brother and friend have the 512mb OLED version

The oled version can run, but it was not possible before

Any updates on this?

Setting LD_PRELOAD="" stops the game from crashing but it seems to just hang forever.

I created another suggestion to allow support for non steamos devices: https://discord.com/channels/1128946232207888414/1135844557133709465/1363762033258139771

My brother and friend on the OLED version couldn't get it to run but after many updates the game now runs on the Steam Deck OLED models

One of this game's developer (game director) have explicitly denied linux (proton) support. (game's behavior of running on native steam deck hardware is unchanged for now, though.)

edit: found this message here in this issue. let me post it again, I have no comment on this. https://www.reddit.com/r/pcgaming/comments/1er6s48/comment/li1m5yq/

Would be interesting to see of the Lenovo device with official SteamOS also works
or if it is actually somehow bound to hardware.

As the user tripod reported on protondb days ago, the game does launch since GE-Proton10-5:

Tinker Steps: Custom Proton: GE-Proton10-5, Set launch options
gamemoderun %command

Okay, I'm kind of on the fence about this, but if you use GE-Proton10-5 you can succesfully play the game no dramas. Obviously there is risk of account getting nuked due to ACE has only steam decks whitelisted

Unfortunately, at least for me (tried GE-Proton10-6 and GE-Proton10-8), the anti-cheat crashes the game right during the splash screen:

There are more reports that it is working in latest Proton versions, but I still couldn't get past the splash screen.

Pretty sure EM stands for the developers name Etaash-mathamsetty

Yes, that's what I've tried.

Proton EM contains patches that bypass this game's anti-cheat client which obviously violates this game's ToS and can leads to ban, please refrain yourself from trying it out.

It's not a bypass btw, but either way you should not use it

Yes the game got updated, newer version of ACE no longer works with the original patches. Tbh Delta Force seems like a fun game, might download it and play with the updated patches ;)

Oh, I see. It does seem quite fun, shame they aren't interested in supporting Linux desktop.

If the initial game launcher fails to start with a "4/77" error or any other network related messages, set the "PROTON_SET_GAME_DRIVE" variable to true.

Just putting this here as it looks to be a problem for some users.

Could it be that the standalone installer does not work at all on proton? The installers pop up but then does not download the game/launcher and hangs in the “initializing” status with 0%.

I already set up the environment variable with PROTON_SET_GAME_DRIVE=1 but did not help…

I tested the latest proton version (bleeding edge) and ge-proton10-25.
