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 HD 2900 XT is rather fast and very close to the GeForce 8800 Ultra. The Radeon HD 3800 have lower performances but although the HD 3870 is behind the GTX and GTS 512, it still surpasses the GeForce 8800 GT. The Radeon HD 2600 XT is ahead of the GeForce 8600 GTS but these 2 cards remain largely behind.
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. Also, for some unknown reason, it was impossible to activate antialiasing on the GeForce 8800 and 8600 GTS.
In DirectX 10 mode, GeForce 8 performances are similar to what we obtained in DirectX 9. On the other hand, for the Radeon, performances are strongly reduced for the Radeon HD 2900 XT while more moderately so for the Radeon HD 3800s. In the end, the 3870 surpasses the HD 2900 XT in this test.
Note that it is not yet possible to activate antialiasing in DirectX 10 mode for Nvidia and AMD.
