guy on steam forum said this
I searched the official game forum, and apparently the single player will still show as version 1.0 after the patch. When you start the game after the patch, your GFWL status will show as "online". This is usually a good indication that the update was correctly applied.
*Avoid the urge to verify the game cache through Steam, as this will mess up the patched version.* (Steam version is 1.0 and will overwrite the patched version)
