Yep, I use that WINEDEBUG=+loaddll too. Just had idea for sake of insterest to compare which calls goes through Wine and in Windows itself, with "WINEDEBUG=+relay" got output file, tonns of wined3d calls... )) I forget that Process Monitor (by "Sysinternals"), can list all those DLLs just in its window, using filter "Process and thread acivity", seems this is more simple way. ) Ok then, so xptruss must be useful for those who interesting with DLL calls debugging info (in native system). :)
