Performance in Simulators
Race Driver: GRID

We have to say it once again: even dual-processor solutions are overkill for this game at every display mode including 2560x1600. Still we can note that the Radeon HD 4890 3-way CrossFire is in the lead and is also the quietest and most economical in its class (if words like quiet and economical can be applied to such solutions at all).

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.

The multi-GPU solutions show their potential and are indeed useful in this game if you want to play at resolutions of 1920x1200 and 2560x1600. The multi-processor products vary in scalability, though. The Radeon HD 4890 platform has a 15% performance growth when switching from two to three GPUs at 2560x1600, but the GeForce GTX 285 platform offers a twofold performance increase then! When a fourth GPU is added to the RV770-based platform, its performance increases by 60% more.
Unfortunately, we could not benchmark the GeForce GTX 295 pair in Quad SLI mode but such a subsystem would probably be limited by the amount of local graphics memory at 2560x1600 as is indicated by the results of the single GeForce GTX 295.
