Performance in Simulators
Race Driver: GRID
The Sapphire HD 4850 X2 is 14 to 29% ahead of the Leadtek WinFast GTX 280 in the first three resolutions, both cards providing highest possible comfort. Moreover, the Leadtek may even seem preferable as it is a quieter and cooler card. However, the gap grows up to 58% at 2560x1600 which is a serious advantage. Once again we must acknowledge that ATI’s decision to use multi-GPU technology for top-end solutions was right and this approach works best at high resolutions such graphics cards are intended for.
X³: Terran Conflict
The specific feature of this test is in wide fluctuations of the frame rate which can easily vary from 12 to 100fps depending on the scene. Neither of the two opponents has a bottom speed higher than 20fps at 2560x1600, so neither of them can be used to play the game at that resolution comfortably. As for the lower resolutions, the Leadtek can only provide a comfortable speed at 1280x1024 and the ATI/Sapphire team scores another point.
