Additional Comments

Work great multi player works ok but not best. I found that the high ping and lag was due to my video card and drivers. The 295.40 was the cause of the issues which are fixed in the 295.49. The problem was known to Nvidia for the 8*** series cards and others. I got around 60FPs to 30Fps with Q6600 @ 3.0Ghz and 8Gb ram. The fire was rendered correctly too.

- To get past the "Incomplete Installation" error:

Use 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
   This increases performance by 50-60 fps in most places for me.  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.

- To get past the crashing/restarting/broken game files which occurs every few minutes during gameplay

Add -lv to the launch options in Steam.  This enables low gore mode, which for some reason fixes the problem.  Low gore mode doesn't look as great, but it's worth it for the stability.
