Core dump in Cities Skylines / Linux

[gojul91]

Hello,

Yesterday evening my Cities : Skylines was working fine and now (while I did not edit its settings) it keeps constantly crashing. Launching Steam from command line shows the following :

Configuration :
Kubuntu 14.04.2 LTS (64 bits)
Intel Core i7 4790
32 GB RAM
X.org server 1.16 (as shipped with Ubuntu 14.04.2)
GeForce GTX 970 w/ Nvidia driver 346.47
Latest updates of Cities Skylines installed (version 1.0.6b)

The issue is not a problem of corrupted savegames as the crash occur even when no savegames are loaded (actually just after a few seconds once the main menu shows up).

The only noticeable thing appearing is that libtiff5 has been updated for Ubuntu today.

The bug seems to be only localized to Cities Skylines and does not affect other Colossal Order games like for example Cities in Motion.

I tried to delete my whole Cities : Skylines config but the bug is still there, so I restored the config.

Could you please provide me some support ? (or some way to reset the graphic settings as they do not seem to be located in the ~/.local/share/Colossal\ Order folder)

I have exactly the same issue. If it is of any help, I've pasted ~/.config/unity3d/Colossal Order/Cities: Skylines/Player.log to https://bpaste.net/show/f822f8def5f2. Please let me know if you want to take a look at the core dump or if I can provide any other information.

Hello,

I've seen some interesting thing with updating file unity3d prefs :

Change line <pref name="UnityGraphicsQuality" type="int">6</pref> to <pref name="UnityGraphicsQuality" type="int">5</pref>

Start the game. It stopped crashing for me this way. (And interesting ly the value came back to 6...)

sebastian -> could you detail your system please ? (I did not get your stacks unfortunately)
