Performance in Simulators

Colin McRae: Dirt 2

We enable the DirectX 11 mode for graphics cards that support it.

From a gamer’s point of view, there is no practical difference between the regular Radeon HD 5870 and the premium-class Matrix 5870 as both allow using any resolution up to 2560x1600, the frame rate being never lower than 38 frames per second. Overclocking may only be interesting from a theoretical standpoint. Take note that the Radeon HD 5870 cannot catch up with the GeForce GTX 480 at the two lower resolutions even if overclocked to a GPU clock rate of 1 GHz. This must be due to Nvidia’s modern solutions being more effective at processing in-game geometry.

Tom Clancy’s H.A.W.X.

The game’s integrated benchmark cannot report the bottom frame rate. We use DirectX 10 and 10.1 modes here.

It is at the resolution of 1600x900 that we can see the biggest effect from our overclocking. There is almost no such effect at 2560x1600 even if the GPU frequency is increased to 1 GHz. The Matrix 5870 ensures a subjectively smooth gameplay anyway whereas the GeForce GTX 480 is challenged by the Radeon HD 5970.
