Radeon HD 4890-matching performance in Race Driver: GRID, but the 2,560x1,600 result should be taken with a pinch of result. The benchmark would often chug along during certain sections, bringing the average frame-rate down. Indeed, after actually playing the game and recording the results via FRAPS, we'd take the single-card HD 4890's performance here every time. Again, it seems to be a driver-related bug.
