Yep I have the 2gb version. I have not gotten very far in the single player but I am using about 700+ mb of vram. I can't say anything for multiplayer yet. If I am going to go over 1gb in this game, I bet it would be there. I'll keep you posted if anything changes. EDIT: On the second level I hit 1340mb used, about 1100mb+ constantly and the dog fight mission I was around 950-1100mb for most of the mission. On Caspian Border I am nearing 1600mb used all the time. EDIT 2: The latest beta (beta 8) of MSI afterburner can track GPU memory usage in real time if that is easier for people.
