Additional Comments

Alt-tabbing works kinda. The game can go nuts for about 30 seconds and then all is well again. In a very long game alt-tabbing a couple of times ruined the game. It started going nuts and eventually the graphics became more corrupt and the whole map turned dark. Wine spewed out lots of GL warnings and a bit later the game crashed. Verdict? Alt-tabbing is still a dangerous thing to do here so you should save before doing so! That alt-tab crash happened in a game that I was playing for over 2 hours straight!!! No problems except for the alt-tabbing. Just FYI: Turning up the graphics to their maximum works fine.

Getting it to work:

• Use Wine 1.0.1 or higher, the more recent the better
  

• Install Supreme Commander

• Patch SupCom to version 3220 or higher

The patcher won't display anything. It takes a quite a while, but it's definitely doing something!
This patch is essential, since it disables the (broken) DVD check

Starting with Patch 3251, the patcher might fail. To test it yourself, you will need Mono, gdiplus, dotnet20 and vcrun2005 (use winetricks). Good Luck.
If that doesn't work, try installing the patches in a virtual machine running Windoze or stick with 3220

• In order to get sound:

Use a recent winetricks to install xact
You may also need to set your sample rate to 48000 in winecfg's Audio tab

• You will need d3dx9_36.dll. If it's missing, get it from dll-files.com, extract and put it into windows/system32

• Create the registry string HKCU/Software/Wine/Direct3D/OffscreenRenderingMode and set it to fbo
  

• Make sure your Color Depth is set to 24 bits. Otherwise the game will not render fonts or 3D models correctly

• cd into Supreme Commander/bin and launch the game with wine SupremeCommander.exe

If you're still running into problems, try starting the game with the /novalidate switch

Also, if SupCom complains about insufficient video memory or crashes very early into the game,
try creating the string HKEY_CURRENT_USER\Software\Wine\Direct3D\VideoMemorySize with a value >64, e.g. 128

Issues:

• Movie frames don't get skipped, so sound loses sync with the video. A faster CPU helps a little bit 
• No network play (requires .net for GPGNET)
• The game may crash when you try to change the resolution. Do it manually in windows/profiles/*user*/Local Settings/Application Data/Gas Powered Games/Supreme Commander/Game.prefs
