Performance in Simulators

Race Driver: GRID

Radeon HD 4770 CrossFireX tandem is not any better or worse than any other contestants, yielding to them in one test and taking over in another. At least, it looks just as good as Radeon HD 4890 or GeForce GTX 275, but will undoubtedly cost less. Even the owners of large 30” monitors will not be disappointed.

We used the in-game benchmarking tools that do not allow measuring the minimal frame rate. We also enabled DirectX 10.1 support for ATI’s solutions.

It must be the amount of local graphics memory, which is only 512MB, that limits the potential of our hero in 2560x1600 resolution. However, in 1920x1200 it is ¼ ahead of the more expensive GeForce GTX 285, and in lower resolutions, it either outperforms the latter or yields to it insignificantly. The gaming is comfortable enough from my subjective standpoint, so two Radeon HD 4770 solutions may be a good choice for the flight sims fans.
