Additional Comments

This is almost identical to my previous test data, except that now you can play the game. If you are getting stuck at the "Incomplete Installation (2)" error, then you can get around it by doing the following: 1. Install the L4D2 demo using Steam 2. Quit Steam 3. Download this gzipped tarball (~14 MB): http://www.tghost.co.uk/wine/steamappscommon.tar.gz 4. Extract that into the steamapps/ directory: ~ $ wget http://www.tghost.co.uk/wine/steamappscommon.tar.gz ~ $ cd .wine/drive_c/Program\ Files/Steam/steamapps/ steamapps $ tar -xvf ~/steamappscommon.tar.gz This will overwrite a few existing files, create some new directories, and create some new files, all inside the steamapps/common/left\ 4\ dead\ 2\ demo/ directory. 5. Launch the game using Steam The files for the tarball were got by comparing the md5sum of each file of a successfully installed version of the game on a Windows box to the partially installed version in Wine to see what the difference was.

- To get past the "Incomplete Installation" error:

Upgrade to Wine 1.1.35 or later

- To get past crashing at the MOTD display when joining a multiplayer game:

Either: Use native urlmon.dll (can be limited to just left4dead2.exe),
Or: Use wine-1.1.27 or earlier.

- To improve the performance

1. Enable multicore rendering.  This increases performance by 10-15 fps in most places for me.
2. Use the following patch:
   http://bugs.winehq.org/attachment.cgi?id=24812
   Note that you may need to minimise/restore or otherwise lose and regain focus of the game to fix the flashlight and some textures if using this patch.
   The performance is so much better in wine-1.1.33 that this doesn't seem to be needed any more.  The framerate with this in wine-1.1.32 was still higher than the framerate without this in wine-1.1.33 though.
