Left 4 Dead 2

What works

Practically everything. The game is a little choppy at the beginning, but after a while everything runs fine.

 This includes the microphone as well, and I could not find anything else that wouldn't work.

What does not

Nothing I noticed so far.

Workarounds

What was not tested

Playing all the campaigns and all the modes. Online play on dedicated servers. Playing on local servers with friends worked however, so I'm going to assume that it works.

Hardware tested

Additional Comments

I did not change anything in the registry apart from setting video memory to the correct amount. Because of some minor flaws (slight freezes and so on), I'm rating this only Gold.

- 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.
