Supreme Commander

What works

Campaign, load and save.

Alt-tabbing the game.

Running it at 1920x1080 resolution at almost max graphics settings (except fidelity).

What does not

Setting fidelity to High makes the game to freeze on the first in-game frame.

For fresh Wine installation (not doing any winetricks), sound is missing completely: nothing from videos, menus, in-game, etc.

Workarounds

Setting fidelity to Medium or Low avoids game freeze.

Using winetricks dbghelp xact solves the missing sound issue. Note that dbghelp is mandatory together with xact, otherwise game starts with black screen and does not load.

What was not tested

Multiplayer.

Hardware tested

Graphics:

• GPU: Intel
• Driver: open source

Additional Comments

winetricks dbghelp xact and ready to play. Performance is really good on my integrated Intel 630 graphics! Setting all graphics settings to High and fidelity to Low makes it possible to play seamlessly on integrated graphics.

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
