Gains en 1920x1200
We put the performance gains from tests into graph form so that they could be interpreted more clearly. They represent the gains of triple and quad GPUs when compared to dual GPU systems and enable us to see the interest of using more than two GPUs at the current time.
If there are no results, this means that the multi-GPU system had a bug that made the game unplayable. A gain of 0% indicates either that there is no gain or that it reduced performances. In the latter case, it would be deactivated by the user. Therefore there are no negative scores. Note that when comparing gains between Radeons and GeForces, you should keep in mind the difference in performance levels, meaning the former are generally less CPU limited.
Gains from Quad SLI aren’t too convincing and the 4th GPU doesn’t seem to add much compared to the 3rd.
S.T.A.L.K.E.R., Rainbow Six Vegas and Bioshock are not taken into account when calculating the averages because there is no antialiasing 4x support for them with the Radeons.
In DirectX 10, Crysis saves quad SLI’s good name.
You may recall that antialiasing doesn't work with Radeons in Bioshock.
