I have an issue. I played the game for a couple of minutes and then all road started to turn black when building. Now everytime the road is black on placing them And big black blocks are cutting my view, unplayable.

Even on a new map, now the black blocks are at the beginning. I disabled the steam overlay and i checked the files for integrity. I even deleted the content and redownloaded it. No solution so far.

Another issue is, that the game freezes when I try to save. Even the system freezes as well



System specs:

Ubuntu 14.04 LTS, Intel i7-2600K, 8 GB RAM, Radeon R7 240 2GB DDR.

Funny sidenote: at the devinfo.txt file (... .steam/steam/SteamApps/common/Cities_Skylines/devinfo.txt) it tells me different GPU VRAM information (512M)

Model: PC
OS: Linux 3.13 Ubuntu 14.04 64bit
Language: German
CPU: Intel(R) Core(TM) i7-2600S CPU @ 2.80GHz (8 core(s))
System Memory: 7962
Gfx Device: Gallium 0.4 on AMD OLAND
Gfx Version: OpenGL 3.0 [3.0 Mesa 10.1.3]
Gfx Memory: 512
Gfx Shader Model: 30
Game Version: 1.0.5

but dmesg | grep VRAM tells me this

[ 20.820799] VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Oland PRO [Radeon R7 240] 2048M VRAM (prog-if 00 [VGA controller])
[ 20.820800] radeon 0000:01:00.0: VRAM: 2048M 0x0000000000000000 - 0x000000007FFFFFFF (2048M used)
[ 20.820805] [drm] Detected VRAM RAM=2048M, BAR=256M
[ 20.821001] [drm] radeon: 2048M of VRAM memory ready

is there a coincidence with my issues?
By the way, how can I check the current FPS and where do I find some kind of debug/error log?

As looking through my logfile at .config/unity3d/colossal.../player.log it in both:

ideo_sync GLX_SGIS_multisample GLX_SGIX_fbconfig GLX_SGIX_pbuffer GLX_SGIX_visual_select_group GLX_EXT_texture_from_pixmap GLX_INTEL_swap_event
Setting maxVSyncInterval to 4
GL: Detected 512 MB VRAM
Total system RAM: 7962 MiB
Initialize engine version: 5.0.0f2 (0)

that it only detects 512 MB

Here is my player.log (i anonymized username and steamid) http://pastebin.com/2cNeYb64

Oh, that's strange. But why? Do you have any idea? Is this a bug in this game? Or is this due to the OpenSource radeon driver/mesa?

Here is a terminal output (this is the real VRAM of my graphic-card):

dmesg | grep VRAM
[ 10.834674] radeon 0000:01:00.0: VRAM: 2048M 0x0000000000000000 - 0x000000007FFFFFFF (2048M used)
[ 10.834679] [drm] Detected VRAM RAM=2048M, BAR=256M
[ 10.834841] [drm] radeon: 2048M of VRAM memory ready
 
I can't tell you more, other games working fine. Even the wine emulated games like World of Warcraft and League of Legends working like a charm (and using memory above 512 mb).

I think the problem(s) are not only on Linux. If I look in this forum, there are many other threads with graphical issues on Linux and Windows. I think, we have to wait for the next bug release.

Because of the wrong VRAM output, I have open a new thread, but at the moment, the thread is waiting for approval by a moderator.
