RV770: AMD ATI Radeon HD 4870 - Race Driver: GRID
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 pickup 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 32-bit version of the game, which is unpatched and running in DirectX10 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 framerate 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 track, barriers, and car bodies suffer considerably from aliasing and are a constant distraction.
All in-game settings are set to their maximum and we test with 0xAA, 4xAA, and 8xAA. Transparency anti-aliasing is also manually turned on through the driver, though this is obviously only enabled when normal AA is being used in-game.
The good news continues for ATI in this title, even given our limited test subjects. So much does the HD 4870 like this game that it even beats nVidia's flagship GTX 280. This is hugely impressive stuff.
