DX11: DiRT 2
DiRT 2 (DirectX 11)
DiRT 2 is a great rally and off-road racing game that was released on all the major consoles as well as the PC just this past winter. DiRT 2 was the first major PC title to implement DirectX 11 features and image quality enhancements and thus makes a great choice for one of our first NVIDIA versus AMD DX11 comparisons.
DiRT 2 Test Settings
DiRT 2 and the NVIDIA driver appear to have some differences of opinion as we did not see the consistent scaling with the SLI configurations as we had expected. It seemed that at some point in our gaming, the system just reverted back to a single GPU rendering scheme rather than using both for performance improvements. You can clearly see those points in time on our line graphs yet also see that before that change happens there is SOME scaling going on with the GTX 480s and GTX 470s at the 2560×1600 at least. For now, I would consider DiRT 2 to be a miss for NVIDIA in terms of multi-GPU scaling and until they can get this cleaned up don’t expect much from it.
