Hold the mouse over the graph to get absolute performance.In the heaviest games in these conditions, Windows 7 shows itself more efficient, sometimes a good deal so, as in S.T.A.L.K.E.R. Clear Sky. Nevertheless the gains, as significant as they are, come at a very low overall performance level, which means that the games remain unplayable in practice.
Windows Vista is the least efficient here with Windows XP in front in ArmA 2 and in Quake Wars with the Radeons.
