Additional Comments

I'm using a non-patched version on wine 1.1.35. The performance is mostly pretty good (not sure how much but my guess is about 20-30 FPS) but in certain places the FPS drops a lot (in Dark Carnival at the hillside for example). Sometimes the game seems to spam a lot of messages (shown in captions) that don't make any sense and resulting in a crash shortly afterward (not sure if this is a bug in the game itself or is it because of wine) I got the MOTD to work after using a dll override to urlmon.dll (set as native) Rated silver because the game works quite well but isn't working well enough for gold. My system specs: CPU: AMD Athlon 64 X2 5000+ (dual core) GPU: nVidia GeForce 8500GT 512mb RAM: 2gb DDR2-800MHz Motherboard: Asus M2N

- 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.
