Symptoms

On starting the game, it crashes after briefly loading. I expect a pre-rendered video is the issue, but no versions of Proton I've tried including GE seem to get it working past the menu screen on my end.

Reproduction

• Open the game.
• Click New Game or Continue.
• It crashes.

Have tried every permutation possible to try and get it working on my system:

• mesa with and without LTO
• launch args with and without mangohud gamemoderun
• Steam native and runtime versions

Notably:

• EAC never works properly on any of these configurations despite working on other users' machines
• the game crashes immediately if taskset is used at all

UPDATE: It seems that Steam's preload may have been the root cause of my problems regarding EAC and the game not letting me play. After verifying the files, the game patched ~35GB and downloaded ~800MB and EAC now seems to allow me to log in. I can also now actually get past the first loading screen.

Game launches and runs fine here, at least during the first mission.

~However, I'm having issues getting the game to use my Dualsense controller (Flatpak Steam). Tried fiddling a bit with Steam input but no luck so far.~ Fixed by using gamescope.

From Easy Anti-cheat window: "Launch Error" "Unexpected error. (#1)"

This system uses the same game install folder for 2 (two) users. However each user has its own game-running-software in the $HOME directories--Easy Anti-cheat; Proton; runtime_sniper/solder, etc.

Running Steam from console show no permission errors (anymore).

~~I played the first 10-11 mission. But my game seems to freeze when I fight Balteus. Does anybody else got this issue?~~ Found my issue. It seems that resizable bar made the game freeze on this fight. This is not the first game causing issues with rezisable bar on my system. So I don't think it's Armored core related.

Game also crashes for me a few seconds into the Balteus fight in the Watchpoint level. This is a few hours in and 100% repeatable.

Guess I'll have to try disabling resizable BAR.

Edit: Disabling resizable BAR did not help.

[Blisto91]

@brandonegbert are you to provide a save game if they are sharable? 👀

[HansKristian-Work]

Reproducing this is going to be a nightmare if we cannot share saves. I'm seriously struggling getting past the tutorial boss ...

[DonKatsu]

Not having any problems with my 5900X+6700XT yet, besides lower performance than I would have expected.

But while experimenting with WINE_CPU_TOPOLOGY I managed to get the game to crash as it launches after the EAC popup. WINE_CPU_TOPOLOGY=12:0,1,2,3,4,5,12,13,14,15,16,17 to contain the game to the first CCD crashes every time. steam-1888160.log WINE_CPU_TOPOLOGY=12:0,1,2,3,4,5,6,7,8,9,10,11 for just physical threads of both CCDs works.

The game that lead to me finding out about WINE_CPU_TOPOLOGY, Mechwarrior Online, doesn't crash with the first option.

[HansKristian-Work]

I got past the boss and grinding through the (trivial) missions ...

[elijahsgh]

~~I'm stuck at "[Press Any Button]"~~ Disregard, I guess. Maybe I wasn't giving it enough time to compile shaders or something. It seems to work fine now.

[HenrikDK2]

My game was running completely fine for 4 hours, but that was until I got to the boss: "AA P07 Balteus". The game keeps crashing when he does a flamethrower spinning attack, it's the second move he does upon entering combat. I've crashed at the same point 6 times now, I've tried different Proton versions like 7.0-6, 8.0-3 and experimental.

[frozen-sea]

Also getting the Watchpoint/Baltheus crash. Both on Proton 8 and bleeding-edge. The annoying part is it happens on the end boss of a lengthy level and you have to start it over every time it crashes. Will continue testing.

• Nobara 38, kernel 6.4.10

Saves are too big to upload here and don't compress at all, so here a link: https://drive.google.com/file/d/1HJ5uHyvlOEP7mtbbAofGBeee6ycounn6/view?usp=sharing Saves are found in (guessing the numbers folder might have different numbers): pfx/drive_c/users/steamuser/AppData/Roaming/ArmoredCore6/76561197967793517/

[brandonegbert]

Looks like @frozen-sea got you a save game but if you need another I can get one uploaded tonight.

[frozen-sea]

On a hunch, I started by trying it in offline mode without the anti-cheat. Was able to make multiple attempts lasting several minutes each (even got him to below 50% once!) at the boss in question without crashing, where as previously it would crash within like 30 seconds.

Launch option: eval $(echo "%command%" | sed "s/start_protected_game.exe/armoredcore6.exe/")

Adding log of that session for good measure. steam-1888160-nocrash.zip

Edit: I then un-did the workaround and can no longer reproduce it on Proton 8 with no launch options... Literally nothing else has changed, not even rebooted.

[kzdixon]

For anyone that has it working: are you on RDNA3 at all?

[Italo-ols]

I'm having the same issue

Arch, kernel 6.4.12, nvidia 535.104.05, proton 8.0-3/bleeding-edge, Hybrid and dedicated graphics tested. System: Intel i5 12500H, RTX 3050 mobile and 16 GB of ram.

I've already tested a variety of graphics combinations, but with no luck.

Edit: I forgot to mention the issue only occurs at the start of the chapter 1 last boss as it was mentioned in another comment. But to add: I could reproduce the freeze as well on the Strider mission setting the graphics settings to low (from normal or high) for some reason.

[HansKristian-Work]

I cannot reproduce any hang on RX 7600. Finally got to the boss after playing this all day <_<

[HansKristian-Work]

I can reproduce it on 5700xt however.

[Sporesirius]

Steam Overlay doesn't work. I had this problem also on Elden Ring. idk If that has something to do with that, but the Easy Anti Cheat slpash screen has the Steam Overlay.

[DonKatsu]

Couldn't beat it but I got Balteus to about 25% left on the second phase without a crash of any sort. That super assault armor attack of it tanks my fps to 30 every time, though... Still 6700XT.

[sanyokbig]

Tried @frozen-sea solution of disabling EAC, but unfortunately it doesn't do the trick for me - game still crashes at around boss's second salvo, never experienced a crash before this mission.

Using Nvidia RTX 1650 Mobile (535.98), with AMD Ryzen 5 4600H on Arch Linux 6.4.11-arch1-1.

[lostpolaris]

Tried disabling EAC, tried some other suggestions including: reducing graphics fidelity and disabling auto-adjust but I also kept crashing on the first salvo of Balteus.

My only solution was to get AC6 on my Steam Deck and then beat the boss from there.

Now I have a 100% reproducible error on the mission immediately afterwards. Where 'restart from checkpoint' will cause my system to crash on the fight with 'The Cleaner.'

[HansKristian-Work]

Finally root caused it. It's a game bug.

It crashes in a shader which samples a texture, but there's actually a uniform buffer there, which causes GPU crash:

Using descriptor QA also masks the bug since invalid access will be turned into a NULL descriptor.

How did you manage to start it at all? My easy anti cheat launcher just is stuck "Initializing" indefinitely. nvidia 3090 on ubuntu 22.04

There's a handful of reports of similar crashes at the start of the Balteus fight on Windows in this thread: https://steamcommunity.com/app/1888160/discussions/0/3820795131605892308/ And this one: https://steamcommunity.com/app/1888160/discussions/1/3820795131608400290/

May not be isolated to Linux.

With this, the threads got cross-referenced. I wonder if there could be a proton workaround for the problem or if this can only be fixed by the developers. I really appreciate the finding, and I wonder how we could report this to Bandai to get this fixed asap.

Finally root caused it. It's a game bug.

It crashes in a shader which samples a texture, but there's actually a uniform buffer there, which causes GPU crash:

Create a new mesa issue and request a workaround: https://gitlab.freedesktop.org/mesa/mesa/-/issues

GiGurra did you try @frozen-sea launch option? That workaround gets the game to start on my machine: eval $(echo "%command%" | sed "s/start_protected_game.exe/armoredcore6.exe/")

Timon was having a similar EAC launch issue on windows: https://steamcommunity.com/app/1888160/discussions/0/3820795131605739862/?ctp=3#c3820795131606924426

Timons windows solution:

1. Go to Library > right click > manage > browse local game files
2. Go to the Game folder and find start_protected_game.exe
3. Right click the app, Properties > Compatibility > Change Settings for All Users > Run this program as administrator
4. Do the same for armoredcore6.exe, and the game should finally load.

However, I read that wine by default runs programs with administrator previlages. Does someone know how to confirm administrator previlages for start_protected_game.exe and armoredcore6.exe running in Proton?

[Cyber-Oto]

I was finally able to finish Balteus without crashing - in offline mode without the anti-cheat by using @frozen-sea launch option:

eval $(echo "%command%" | sed "s/start_protected_game.exe/armoredcore6.exe/")

Replying to https://github.com/ValveSoftware/Proton/issues/7045#issuecomment-1694143730

I did try running the armoredcore6.exe instead of the eac launcher, like was suggested here, but that only launches, turns into a black screen with game cursor, and then 1 second later closes.

[HandsomeToast]

I am currently still running into the issue of starting up the game I get a white screen for about 4 seconds with a curious that I can see and moves when it goes to black my cursor is gone and the game crashes anyone any advice I tried everything in these guides

If I try to add extra commands to the eval part e.g. gamemoderun mangohud %command% - game crashes either with white or black screen. Removing gamemoderun and using only mangohud %command% does work for me, tho.
