Assassin's Creed Revelations (201870)

Whitelist Request

• Name of the game to be whitelisted: Assassin's Creed Revelations
• Steam AppID of the game: 201870

System Information

• GPU: GTX 1070
• Driver/LLVM version: 396.54.09
• Kernel version: 4.15
• Link to full system information report as Gist: https://gist.github.com/d10sfan/b50576f1a783a2a3510d3e14478aaac1
• Proton version: 3.16

I confirm:

• [ ] that pressing the Play button in the Steam client is sufficient.
• [ ] that runtime config options are necessary to run the game.
• [x] that no workarounds other than the mentioned ones are necessary.

Issues

• [ ] I haven't experienced any issues.

• [ ] There are no issues left open for this game.

• [x] Although I consider the gaming experience equal to Windows there are remaining issues:

• The bundled uplay seems to crash. I downloaded the installer from ubisoft's website and installed it inside the prefix, and then it loaded.

• Core fonts were required to show the uplay window

• Once all of this was taken care of, the game itself worked great.

These were not the only steps necessary:

1. Uplay couldn't connect to the server, workaround as described in this issue: https://github.com/ValveSoftware/Proton/issues/727

sudo ln -s /usr/lib/libgnutls.so.30.14.11 ~/.local/share/Steam/ubuntu12_32/steam-runtime/pinned_libs_64/libgnutls.so.26
sudo ln -s /usr/lib32/libgnutls.so.30.14.11 ~/.local/share/Steam/ubuntu12_32/steam-runtime/pinned_libs_32/libgnutls.so.26

2. When I finally got into the game, there was a graphical glitch, with a white overlay "fog" covering the entire screen. The solution was to rename systemdetection.dll as described here: https://steamcommunity.com/app/201870/discussions/0/1520386297687444769/

No idea if there are any side effects.

The above fix does not work on Ubuntu 18.04 - the location for the libgnutls.so.26 in the steam folder doesn't match - on Ubuntu there already is a symlink located in ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu

while the /pinned_libs_32 and /pinned_libs_64 don't exist, creating them does nothing.

The game does not open with an error about failing to request a product key from Steam like in this error https://github.com/ValveSoftware/steam-for-linux/issues/5649

This game seems to work perfectly fine. Even a game breaking bug of the windows version is reproduced. I'm talking about this one: https://linustechtips.com/topic/1198968-assassins-creed-revelations-randomly-started-crashing-sequence-7-memory-3-fixed/ I'm looking for a way to force proton to only use a single core, as this seems to fix the issue under windows. Does anyone know how I can do this?

Hello @cverstege, you could try setting the game's launch options to taskset -c 0 %command%. This should tell the game to only use the first CPU core (the count starts at zero).

Thanks for the quick answer. This indeed fixed the issue. But then I got low fps. I managed to complete the mission now. So adding this permanently to the launch options is not a good idea. Thank you very much @kisak-valve
