Bioshock
The first game based on the Unreal Engine 3.0 to support DirectX 10, Bioshock has great graphics even in DirectX 9 mode while it is less resource heavy than Rainbow Six : Vegas. We carry out a well defined sequence of movement with all options pushed to a maximum.
In DirectX 9 mode, the Radeon 3870 X2 isn’t surpassed by CrossFire and it has a large lead on the GeForce 8800 Ultra.
Like with Rainbow Six : Vegas, Nvidia allows the activation of antialiasing for this game which doesn’t normally support it while AMD doesn’t offer this option.
In DirectX 10 mode, performances improve significantly with the latest driver provided by AMD. This allows a single Radeon HD 3870 to nudge its way next to the GeForce 8800 GTX. On the other hand, with multi-GPUs performance gains are less than with DirectX 9. Nonetheless, it is still enough for the Radeon HD 3870 X2 to be ahead of all Nvidia cards.
Note that it is not yet possible to activate antialiasing in DirectX 10 mode for Nvidia and AMD.
