Pretty much everything related to the main game executables, as far as I can tell. It's a little slow on the machines I used it on, but said machines are not exactly what I'd call powerful anymore and there is always some overhead involved with running things in Wine.
What does not
Decal. Someone made a patched version of an ancient version of Wine that could run it, but I can't find it anymore and I doubt it'd work with modern versions of Linux anyway.
What was not tested
Multiple client software. I didn't test it because I don't have a need to be on more than one server at a time, and I only have my one account.
I used a 32-bit WINEPREFIX to run this, as this needs ie7 or ie8 to work and those won't work with a 64-bit prefix in my experience. Winetricks packages used are: d3dx9 (might work with just a couple of the d3dx9_xx dlls but I didn't test with that) ie7 vcrun2005 wininet corefonts
