Performance in Simulators
Race Driver: GRID
A single GeForce GTX 285 is enough for playing this game even at 2560x1600, although this card has the worst result among the tested solutions. The Radeon HD 4890 CrossFireX equals the GeForce GTX 285 SLI because the small advantage of AMD’s solution does not show up in practice.
The 3-way CrossFireX solution fails yet another test, being only ahead of the Radeon HD 4890 tandem at 2560x1600. Again, this gives no practical benefits to the owner of such a noisy and uneconomical configuration considering the overall high level of performance in this game.

We use the in-game benchmarking tools that do not allow to measure the bottom frame rate. We also enable DirectX 10.1 support for ATI’s solutions.
ATI’s single cards do not look very good in this game but CrossFireX technology changes the picture: two Radeon HD 4890 cards in one graphics subsystem show excellent scalability and superb performance at resolutions up to 1920x1200 inclusive. The GeForce GTX 285 does not scale up well in SLI mode, and the appropriate SLI configuration is 37% slower than its opponent at 1920x1200.
This is also the only game on our list where the Radeon HD 4870 3-way CrossFireX platform provides a practical benefit as it makes the resolution of 2560x1600 playable with comfort. The GeForce GTX 295 has a performance slump due to the lack of local graphics memory (it has 896MB as opposed to the SLI pair’s 1024MB).
