Ok i think i found out where it hangs and what is needed to install it in wine

You only need d3dx9_43 and d3dcompiler_43 and the Game doesn't depend on steam so once downloaded you can move it to another wineprefix.

1.) export WINEPREFIX=somedir
2.) winetricks d3dx9_43 d3dcompiler_43
2.) winetricks --no-isolate steam
3.) download the game
4.) cd $WINEPREFIX/drive_c/Program\ Files/Steam/SteamApps/common/Divinity\ -\ Original\ Sin/
mv _CommonRedist _CommonRedist_Backup

^^ the last step stops steam trying to install additional files (not needed and might end up in a looop)

Once this is done you should be able to start the game / create a profile / change gfx settings and so on. Also you should be able to start New Game.
After a while you will be able to create your char's and you should be able to see the intro movie. But when loading Cyseal the game basically stops with using 100%.

But i was able load a stored save from windows after copying all the profile data and cache data from the windows game to the linux folder.
