I've been messing with this all morning.

If I don't close the uplay window then the game just stays a black screen with no sound, though the cursor will change to the in game cursor design.
If I exit out of uplay then the black screen becomes functional and I get the in game warning, however (I think) because I exited uplay, the game window closes a few moments later and there is an annoying uplay background process I have to manually go kill.

I did try to run this through Lutris. I got the same behavior from there as well.

For me, disabling the overlay lets the game launch to the point where it presents the epilepsy warning screen, then it suddenly closes. UPlay is still running at that point, and has to be manually killed - both it and the remaining Anno process.

Switching UPlay to launch in offline mode gets me past the warning screen and into the game proper though, at that point it seems to run quite acceptably, and I imagine that it'll run even better when DXVK is updated. (Without any multiplayer features of course, being offline and all)

For those who are looking for workaround:

1. Run anno with Lutris + tkg-protonified-4.1-x86_64 (you can use set up from Lutris web page)
2. Turn uplay to offline
3. Run Anno in Uplay (It will start wine steam also)
4. Wait for Anno1800.exe process to appear and then kill it (first time)
5. Run Anno in Uplay again
6. Game loads up without "Wine C++ Runtime library" error (if it shows system dialog for application not responding just click wait)

It is wierd but worked for me every time so far.
Although game is kinda laggy (not depending on quality settings - same lag for low as for high) but playable.

Enjoy game!

Edit: Also I'm not sure if its necessary but I have disabled overlays in both Uplay and Steam

Out of the box, Anno 1800 will crash right after the epilepsy warning screen. However, you can make the single player part of the game work by disabling the Uplay overlay and switching Uplay into offline mode.

This can be done by editing the file ~/.steam/steam/steamapps/compatdata/916440/pfx/drive_c/users/steamuser/Local Settings/Application Data/Ubisoft Game Launcher/settings.yml and setting overlay.enabled = false and user.forceoffline = true. Next time you start Anno 1800 via Steam, the Uplay login window opens but won't let you log in because you are in offline mode. Click on "Settings" and unset the checkbox for "Always start Uplay in offline mode", then click on the small "Restart Uplay" button above it. Now you can log in and don't forget to set the "Remember Me" checkbox. After logging in successfully, you can now reenable offline mode (e.g. by closing uplay, and setting user.forceoffline = true in the config file again).

Multiplayer won't work that way, obviously. Also, zooming in/out causes a few graphical artifacts, but that might be solved by a newer DXVK version. Other than that, the game is perfectly playable.

Also, zooming in/out causes a few graphical artifacts, but that might be solved by a newer DXVK version.

If you're referring to shadows, this actually seems to be a (rare) game bug and is usually fixed by restarting the game.

Maybe a possible workaround for the "C++ Runtime" crash:
I guess it's caused by launch combination steam + uplay on newer wine versions.
Tested the game with the first patch and was facing the c++ runtime error on
lutris (tkg-protonified 4.5 faudio / tkg4.6) & proton 4.2-3
tkg-protonified 4.1 worked as described above.
(all with uplay offline mode and both overlays disabled)

Nearly giving up after trying also vcrun2015 from winetricks and win10 configurartion
(uninstalled afterwards)
i used the "Run EXE inside wine prefix" function and navigated directly to "steamapps/common/Anno 1800/Bin/Win64/Anno1800.exe"
(no wine process should be running in the prefix! / it's also working for me with setting executeable path directly to Anno1800.exe in lutris)

Now the game behave different on my system:

• tkg4.6 with uplay in online mode working fine without c++ error and starting with 100% success rate /no multiplayer.
• tkg4.5 faudio crash but without c++ error.
  (Starting the game with Uplay.exe again gives the c++ error like before.)

My guess is that the error is caused by different behavior with the launch parameter "-uplay_steam_mode" from Uplay
[Terminal with Uplay.exe]
UbisoftGameLauncher.exe [deleted] -upc_arguments -uplay_steam_mode
Anno1800.exe -uplay_steam_mode

[Terminal direct Anno1800.exe launch]
UbisoftGameLauncher.exe [deleted] -upc_arguments
Anno1800.exe -uplay_steam_mode

Maybe this can also be tested with proton and steamlinux (overwrite launch command)!?

I'm now able to run the game without c++ runtime error on proton 4.2-3 using a workaround to launch the exe with cmd inside the prefix. The commands marked as NOT WORKING are giving me a "file corruption detected, validate files with uplay" error. Sadly i was not able to adapt the launch command from steam directly.

Feel free to adapt it for your system

Not sure if this is of any help, but I bought the game on Epic Game Store and can, therefore, run it independently in UPlay, and it runs fine for me out-of-box (Wine tkg 4.6, DXVK 1.1.1). No multiplayer since it fails to detect NAT type (or something like that, probably possible to work around somehow), but yeah, just figured I'd throw it out there.

Now Anno starts with the script from "withoutaface" (thanks!). Before i got the C++ error. But graphic looks ugly. The grass and mountains are shown as black. Also some overlays (e.g. talking persons) seems to have missing colors.

I changed the graphic settings from medium to high or ultra. All the same. Screenshot is not possible because the image just shows black screen. I attached a photo from smartphone.

Ubuntu 19.04
rx580
i5-8400
5.1.1-050101-generic (also older ones)

i made a little launcher to start the game directly from steam
(Anno1800 links to launcher; launcher starts renamed exe with cmd).

<Link removed by moderator>

Hello @kisak-valve, okay, thanks for clarification.

I checked with new Proton 4.2-4 but i still get the C++ error popup and game doesn't start. With the startscript from withoutaface it starts but with ugly graphics like i posted before.
Here is my steam.log (started without script directly out of steam).

@Palaix which version of Mesa and LLVM are you using? The game renders fine on Mesa 19.1-git and LLVM 9.0-git, although I personally haven't tested the stable versions with this game yet.

Hello @Palaix @kisak-valve
tested the game today on my second machine with ubuntu 18.04.2 (+hwe) + Proton 4.2-4 and it's starting fine without c++ crash and running with no graphic glitches (~20 fps on wqhd resolution +high settings ).

is proton using python from the system or is it shipping it's own build?

Hi !

I did a testinstall with manjaro (stable) and Anno 1800 is running in steam (offline mode). Everything works on high settings. It's good playable (5 hours ;-)) but it is not 100% smoothly also with low graphic settings.

manjaro: Python 3.7.3-1
Ubuntu: Python 3.7.3-2

Both running with gnome-shell. If there is anything more i can provide just please tell me.

@kisak-valve
Can't find the difference why Anno is running in Manjaro but doesn't work with Ubuntu 19.04. I need a hint what to check, what to log etc. I have both distros running so perfect situation to analyse...
I wonder why @withoutaface can run it even in older Ubuntu release.

Is this glitch normal and expected:

I can't find such problem nowhere. Is it just me?
NVIDIA: 430.40
DXVK: 1.3.1

Happened to me too after the latest update.

Too bad I just tried it for the first time :(

This is already fixed in DXVK as of doitsujin/dxvk@6b2f4f93cc51c7c75dbf4cc067c0b924052d6d35.

Today, Anno 1800 patch 5.3 was released. Since the update, I can't start it anymore using Proton/DXVK.

After hitting "Play", Uplay starts Anno, then a black fullscreen window appears. Instead of showing the intro videos/main menu, that window disappears after a few seconds.
The process(es) still remain (Steam marks the game as currently running), so I need to terminate them manually using pkill.

Disabling the Uplay overlay and enabling offline mode doesn't help.

@kisak-valve When using PROTON_LOG=1, the black window doesn't just disappear. Instead an error dialog pops up (the same one as as in the original post):

This doesn't happen if PROTON_LOG=1 is not set.

The latest update (5.3.893800) seems to have fixed it. I googled at a bit and some Windows users experienced the startup issue, too. Maybe it was just a game bug that was fixed now.

@Holzhaus Hey, hast du es jetzt hinbekommen? Hab die gleiche Fehlermeldung immer noch und weiß nicht was ich noch versuchen soll. Würde außerdem gern online spielen.
PS: Bin neu im Ubuntu Universum

@KoalaLord: I still get the same error message and don't know what to do. I also want to play online.

I removed PROTON_LOG=1 from the launch options. I also had to edit the file ~/.steam/steam/steamapps/compatdata/916440/pfx/drive_c/users/steamuser/Local Settings/Application Data/Ubisoft Game Launcher/settings.yml and made these changes:

overlay:
  enabled: false
# [...]
user:
  forceoffline: true

I don't think online multiplayer works at the moment.

Ubuntu 19.10, just installed the game, changing the settings.yml or the suggested winetricks doesn't help much.

Is this game locked now for use with steam proton? It's not visible in my library anymore if the "linux button" is clicked. Otherwise it says "available on windows" and the install button is grey.
(I had it installed previously on the same machine. did not change steam settings just uninstalled the game)

Using Lutris I found a (Lutris-) version of Proton with which i can run Anno 1800.
This may not be useful for steamusers directly, but I hope that sharing my experiences could help fixing protons compatibility for steam.

Only lutris-nofshack-4.19-x86_64 works nice (except for network features) for me.

I also tried all lutris-proton versions between lutris-4.16-x86_64 and lutris-4.20-x86_64 and the corresponding nofshack-verions, but none of them even launched or they crashed at startup.

I tried the lutris-proton versions based on different Wine 5 versions up to version 5.7. In these version Anno 1800 tells me that the network features would work (I get the green network circle in the upper right corner in the main menu). But when I try to start a new game or continue a previous played savegame, it takes up to 40 minutes of loading screens to get me to the game and then it is really slow (it feels like 5 fps or something like that and it does not matter what graphics settings I used).
I tried different recent dxvk versions, but I did not see any big differences between those runs.

I don't know if these information are useful, but maybe someone who has more knowledge of wine, proton or the lutris proton builds might be able to find out, why exactly lutris-nofshack-4.19-x86_64 is working way much better than all the other versions.

I'm also using Lutris to run Anno 1800 under Proton.
My settings:
Wine version: lutris-5.7-x86_64
DXVK version: 1.6.1L
nvapi and nvapi64 disabled.
DXVK_HUD = 0
PYTHONIOENCODING = utf8
Latest version of the game as at May 2020, however I do not have any DLC if that matters.
I am using Medium settings and it lags for about 30 sec to 1 minute but then framerate improves and it becomes playable.

I am able to run the game with Uplay overlays disabled.
I am also able to run the game in online mode (although I haven't tested multiplayer out yet).

My system is:
Core i5-9600K | 16GB DDR4 | AMD Radeon RX 470 | mesa-git 20.2.0_devel driver
Using Arch Linux, currently kernel 5.6.11-arch1-1

Anno 1800 works fine in Steam/Proton without Lutris/Custom Wine/etc. for me. You only need to start Uplay in offline mode. Network isn't working though, so you can't do multiplayer or use Uplay Club items/buildings/characters.

Sadly I have almost the same experience as @p0kR, but in my case even lutris-nofshack-4.19-x86_64 doesn't work for me. I can summarize this as follows:

• Proton 4.11 and all Lutris 4.* - hangs with black screen after starting the game, doesn't matter if it's offline or online.

• Proton 5.0* and Lutris 5.* starts but takes forever to load a game. And still doesn't matter if it's online or not.

My OS is Ubuntu 20.04 and GPU RTX 2060 SUPER with the latest drivers installed. I've tried also the Nvidia Vulkan beta driver but the same thing is happening. DXVK version I've tried is 1.6 and 1.7. I was thinking that maybe it's because of the NVME drive?

I have the same issue as you, I'm using wine-staging build from master. The problem started when the new content update was activated. I suspect that this update triggered a bug or unsupported feature. I first thought maybe the bug was in the game and asked here:
https://www.reddit.com/r/anno/comments/gw4o03/very_slow_loading_speed_since_the_latest_dlc_was/

I can confirm the extremely long loading times with Proton 5.13. The main menu works fine, but I when I try to load a game it takes forever. The game doesn't lock up (the loading screen wallpapers and advice still change), but nothing happens. I gave up after ~40 minutes and killed the process.

Long loading times seem to be fixed with Proton 5.13.2. It now works out-of the-box.

Remaining issues:

• Online mode doesn't work, therefore multiplayer and all "Ubisoft Club-only items, character portraits, etc don't work.
• Occasionally freezes my system, but that seems to be a driver issue: https://gitlab.freedesktop.org/drm/amd/-/issues/1393
• When opening the Uplay Overlay, the overlay is not hidden after closing it, making half the screen invisible. Workaround is to disable the overlay.

• Occasionally freezes my system, but that seems to be a driver issue: https://gitlab.freedesktop.org/drm/amd/-/issues/1393

This seems to be fixed with mesa 21.0.2. The game still freezes and needs to be killed, but the system stays usable (Ryzen 4800U).

Anyone able to get it running who (1) just bought and installed it now that it has been re-released on Steam, (2) doesn't use lutris, but just runs it through Steam, (3) uses valves proton or tkg/GE, (4) and who didn't already have uplay or "ubifuck connect" or whatever it's called installed?

It refuses to start even once for me. The launcher never opens. The Anno1800.exe process uses 100% CPU until I stop the game. I've tried with Proton Ex and GE. I also tried editing the settings yaml with the suggestions earlier in this ticket, I tried with gamemode and a few other things.

I have a steam-916440.log, but I doubt it's useful to anyone. If it is, I can drop it in here obviously.

Apparently ubi broke the game, but I have no idea:

The 1.16 update is pretty buggy in generell on windows too. Might have nothing to do with Linux. I bought it on steam when it released and it worked fine with Ubuntu. Wait until 16.1 update . Might take some weeks.

Any news regarding the multiplayer issue?

@folknor I match all (1) to (4) in your post. I simply installed it on Arch Linux using GNOME 43 via Steam Proton, selected the last stable version. Ubisoft connect works fine with my account and the game itself runs great, except multiplayer. Also somehow the Ubisoft Connect software apparently can't save my account credentials, I didn't link my Steam & Ubisoft account.

Yes, works for me as well now after the patch. Thank you! :-)

Ok, interesting. What NAT type do you see ingame (upper right corner)?

The normal one. It's green.

@Knogle What does it specifically tell you? Mine is NAT-Type: Moderate and it doesnt work with GE 7.43.

For me, multiplayer also isn't working with GE 7.43. NAT-Type moderate despite having port forwarding enabled.

See https://github.com/ValveSoftware/wine/issues/172 for a fix that made multiplayer work for me.

FYI: Switching to Proton 6.3-8 fixes multiplayer. It seems Proton 7.0 has a regression.

How did you get Ubisoft working with 6.3-8? It is unable to connect in my case.

That's a different problem and it's really a struggle. To get past the "Initializing..." or "Looking for patches..." screen of Ubisoft Connect you need to connect to a VPN or mobile hotspot before starting the game.

@MaxXor You can also change the MTU of your network connection to 1452 bytes. I think that network packages must not be too long for UPlay. By using this MTU (or a VPN or mobile data) the network packages will be smaller.

Same problem here. When the game will load the videos, the cursor changes to the Anno 1800 one, and them the game crashes. Nothing useful spoted in the log files.

What Proton Version are you guys using? For me it still runs fine.

Tried Proton Experimental and the Ubisoft Connect was not opening properly, so switched to Proton-GE-8.15.

Can you try GE Proton 8.10? I use Lutris btw. through Ubisoft.

Now the game is running.

Do anyone tried the mod browser? It simply is not loading the mod browser inside the game.

Hello,

I had reinstalled my computer this week end. when I try to play the game my KDE session freeze and it restart.
Does anyone have the same issue ?

(I use Manjaro)

Seems to be a valve / proton issue. I managed to reinstall UbisoftConnect via Lutris, and all of a sudden, I got a connection. As Lutris also uses GE proton 8.26, something seems to have corrupted the steam proton network settings.

No idea how to configure the steam client connection settings. Starting steam from command line with -tcp didn't help. Will now attempt to play through lutris.

When exiting out of Anno 1800, Steam continues to show the game as "Playing" or "Running" even though it's no longer active.

Anno 1800 is closed correctly, but Ubisoft Connect stays open in the background. It can be closed through the system tray.

Game takes too long to load (more than 2 minutes from first black screen to main menu). There is no sound in main menu and in the game. When starting a game session (new game or loading a previous save) - there are constant freezes, as if the game is interactive for 7 seconds, then the whole interface and the game freezes for 50+ seconds (the mouse can move, I can switch windows with Alt+Tab), then the game works again for 7 seconds, then another freeze for 20+ seconds. This behavior is repeated endlessly, making it impossible to play the game.

In log file i found the lines with errors that repeat at intervals similar to the intervals of freezes:
126843.520:0444:055c:err:sync:RtlpWaitForCriticalSection section 00006FFFEE216CC0 "../src-wine/dlls/mmdevapi/audiosessionmanager.c: g_sessions_lock" wait timed out in thread 055c, blocked by 0614, retrying (60 sec)

Observe (no sound + freezes)

Hi team.

It's been more than 2 months since i posted my request (https://github.com/ValveSoftware/Proton/issues/2544#issuecomment-2746513973) and no one has responded.

I found at least 3 feedbacks with the same problem on ProtonDB site from different users with different hardware/software. So the problem is not just with my laptop. Also I've updated Proton to the new 10 beta version, and have the same issue.

I’d really appreciate any feedback or updates regarding the status of the request. If there’s anything I can do to help move it forward - such as updating the request or adding more tests/logs - please let me know.

@kisak-valve I see that you are the most active team member in this thread, could you tell me how to increase the priority of my request so the technical team would pay attention to it?

Thanks again for your time and for maintaining this project!

@brida-games Disable the ubisoft overlay, vsync and run the game as borderless window. Try using x11 instead of wayland.

If that doesn't work then use Glorious Egg's Proton. You'll probably need lutris and ProtonUp Qt. Install from flatpak to get latest version.

If that doesn't work either, then use a more recent distro and kernel. I played on Endeavour linux, with lutris and Glorious Egg's Proton without any issues.

The Ubisoft Connect application never properly quits when gracefully exiting Anno 1800. This leads to STEAM thinking I'm playing Anno 1800 perpetually until I force it to stop one way or another.

Can we please get this fixed so my compie doesn't just burn CPU cycles/power with the Ubisoft Connect never quitting nicely?
