Yes, I know, and it was before i set it manually, in the list of non-installed Games. But when I tried ingame, nothing happend. Without at least the Ingame Features, what sense is there in using Xfire ? This should be at least working in the Games they claim they support.
I wonder if it has to do with that there is no registry entry (as with a Installer!) for Nexuiz. As far as I know Xfire also looks for registry entries for a Game.
