Race Driver: GRID is the newest game in our testing arsenal and it's currently one of our favourites too. Its combination of arcade style thrills and spills with a healthy dose of realism and extras like Flashback makes it a great pick-up-and-go driving game. It's also visually stunning with beautifully rendered settings, interactive crowds, destructible environments, and stunning lighting. All that and it's not the most demanding game on hardware, either.
We test using the 64-bit version of the game, patched to version 1.2, and running in DirectX 10 mode. FRAPS is used to record frame rates while we manually complete one circuit of the Okutama Grand Circuit, in a Pro Tuned race on normal difficulty. We find a frame rate of at least 40fps is required to play this game satisfactorily as significant stutters can ruin your timing and precision. We'd also consider 4xAA as a minimum as the aliasing on the straight lines of track, barriers, and car bodies is a constant distraction. All in-game settings are set to their maximum and we test with 0xAA and 4xAA.
Finishing off a clean sweep, the HD 4890 again shows itself to be well and truly the best in class. So nVidia's challenge in this price segment really does ride on how the GTX 275 performs when we look at it tomorrow.
