Counter-Strike: Source

What works

Almost everything; See exceptions noted in the next section.
Performance is over 120fps in Video Stress Test.
Relevant CSS/Wine/System Settings and Info

CSS Settings = Model: High, Texture: High, Shader detail: High, Water: Reflect world, Shadow: High, Color Correction: Enabled, Antialiasing: None, Filtering: Trilinear, Vert. sync: Disabled, HDR: Full. HW/SW DirectX level: DirectX v9.0 + clean .wine prefix, *No registry tweaks*. HL2.exe overridden to run as Win98.

OS: Kubuntu 9.10 alpha (Karmic) 2.6.31-5-generic SMP

What does not

The HTML in the MotD is not displayed when joining a server.  (Bug 6095)

Voice chat appears to be suffering a regression and does not work at the moment (ALSA nor OSS).  Clicking "Test Microphone" from the voice options tab does not begin a microphone test (the text never changes to "Stop...").  This is odd, considering voice *does* still work in other Source games (tested using the same, clean, .wine prefix) like HL2 Deathmatch, and in the parent Steam app. (Bug 19620)

When exiting, the game will occasionally abend with a message stating HL2.exe has encountered a critical error.  You may simply close the dialog and continue back to Steam. (Bug 19621)

Additional Comments

Only rating as silver because of MotD and voice chat issues, which can be restrictive to play (and get you banned for not following/knowing server rules -g-). This cannot be rated gold because it cannot be made to work fully by anyone at this time.

All things going well, this game will work in current versions of wine (wine-1.0.1 and up) if you:

1. Install steam and Counter Strike Source from the DVD or via the steam download.
2. Select only "ALSA" sound driver in winecfg. OSS does not work anymore because Steam itself has sound open.
3. Start Steam with the following command:

cd ~/.wine/drive_c/Program\ Files/Steam && WINEDEBUG=-all wine steam -applaunch 240

Note: Your path might differ, depending on language and installation directory. This is default for English install.
Note2: Additional command line options go after-applaunch * not before. Ex: -applaunch 240 -dxlevel 80 -console

For better graphics quality you might want to use -dxlevel 90 command option and enable GLSL shaders via registry (save this to a "file.reg" then import with 'wine regedit file.reg'):

[HKEY_CURRENT_USER\Software\Wine\Direct3D]
"UseGLSL"="enabled"

Note: GLSL is enabled by default as of wine-0.9.49

For better performance use -dxlevel 80 or even 70 and the following game settings:

cl_drawmonitors 0
r_WaterDrawRefraction 0
r_WaterDrawReflection 0

Also you can disable GLSL.

Known issues:

• When starting a game Steam throws an error saying The registry was in use by another process.
  See Steam's HOWTO for possible solutions.
• Counter Strike crashes as soon as it starts or you join a game.
  You most likely have other program(s) using sound. Run winecfg and select only ALSA sound driver. OSS is not the best choice anymore.
  
  For Ubuntu 8.04 and up - kill/disable pulseaudio. It is not compatible with Wine. And will cause all sorts of problems if left running.
  
  Another possible reason - you have "Steam Community In-Game" enabled. It does not work properly on Wine and causes all games to crash. Please disable it in settings -> In-game tab.
  
  On some distros with broken gcc (Ubuntu in particular) in winecfg libraries tab add "GameOverlayRenderer.dll" and set it to "disable".
• MOTD/server description is not visible.
  This is a know bug and is not yet fixed. Some text might be visible but most is not.
• Voice communication doesn't work (for some users).
  There are no known workarounds. Try using alsa as described bellow and using other voice communication software.
• Steam will not work from ntfs partition mounted using ntfs-3g driver (2.6.25 kernels and older)
  This is a known limitation of the driver. Steam requires functionality (mmap with shared write access) which Wine can not emulate if it's not supported on file system. To fix: Install Steam and all content into native Linux file system.
• Game crashes after a few minutes. You can fix this by putting this file into your "~/.wine/drive_c/Program Files/Steam/steamapps/YOURUSERNAME/counter-strike source/cstrike/resource" folder, or by applying this patch. See bug #7698 for more information. 
• Lacking fonts. You need Tahoma and Lucida Console fonts for every text to show properly. Use winetricks to get them if you don't have a windows install handy.
• Game crash after a while
  To fix:
  Run winecfg, click "Add application...", select "hl2.exe" (doesn't matter which one, only the filename is used, not the path) and click Open. Select "hl2.exe" in the list and change the "Windows version" to "Windows 98".

Thoughts -
(i) In the past Steam updates have been followed by serious errors running CS:S (or even just steam), including serious lockups. When running after an update, be sure that you're ready to switch to another tty at the first sign of trouble - preferably having a "wineserver -k" sitting ready in it just in case. Just a thought.

(ii) Sound latency issues (skipping, popping as everything struggles to keep up) - most notably sudden lag during firefights can sometimes be cleared up by running "soundlist" in the CS:S console. This is a more general CS:S issue, nothing to do with wine.

If you have other good resource (at least as good as ones above) send vitamin a message with the link.

Do not change mat_dxlevel if the CS-Source game renderer has been started one time or more. If you need to change it (for example, for join in a server with zblock), change it before you join a server or with the -dxlevel launch parameter. If not, the game will freeze for a very long time. Only try it if you have enough memory (1GB or more) and a good hard disk :)
