First of all, yes, I know the individual parts of Doom3 and am also on fallen zuzulegen.Nein me this edition I ask not predict whether I need to create a Steam account and find that an impertinence beyond compare with the supplied DVD to start nothing without same. Let's see about the fact of Steam accounts across at least I can not say anything to the actual gameplay of this edition because it is not moving around the straining on a least with 8Gb RAM / Quad Core and a 5870 graphics card to run. Even the proposals offered in the Internet do not work, ale drivers are up to date but it stirs nothing but a gray screen followed by an error message that the Doom3 BFG Edition no longer pose no problems funktioniert.Da other games, I recommend times easily Finger away from this version if you want to have no added stress and a functioning operating system is not absurdly "bend" möchte.Meine Edition, not purchased from Amazon but it is still cheaper than bought the usual way in the garbage, unfortunately.
