Single player (campaign & scenarios). Intro with sound, no lag. Ingame animations & sound. Saving and loading.
What does not
Mouse tracking lags a little in full screen.
What was not tested
Multiplayer (hot seat, LAN).
Installs flawlessly on a clean prefix. Works even on a netbook (1.6GHz @ 2GB RAM with Intel GMA 3150). If the mouse lag, try setting the game in virtual desktop in wineconfig, did the trick for me. Platinum since everything works perfectly, no crash after ~2 hours straight, unlike win xp...

To get multiplayer working, you need native directplay dlls. The old howto had a link pointing to outdated directplay dlls which cause problems with wine and generally don't work as expected. However with the latest dplay from DirectX 9.0c multiplayer is (almost - see note for details) flawless.
In the wine wiki is described how to get native direct play dlls.
Personally I would recommend using winetricks directplay which installs dplay dlls and sets overwrite in winecfg, however you may choose do install manually those files in which case you need to:
You can now play Heroes 3 in HD, utilizing the full size of your screen, thanks to Heroes3HD mod. It doesn't change anything gameplay wise.
With recent Wine releases, Wine prefixes are set to Windows 7. Currently, it causes rendering issues when HD or HD+ mod are installed.
winecfg and setting the Windows version to Windows XP solves the rendering issues.
