Performance in First-Person 3D Shooters
The game doesn’t support resolutions of 16:10 format, so instead of 1920x1200 we used a resolution of 1920x1440 pixels that has an aspect ratio of 4:3.
The Nvidia GeForce 8800 GT provides a nice addition to the minimum of speed. At a resolution of 1920x1440, when the amount of graphics memory has an effect on performance, the 8800 GT also enjoys a 26-27% lead over the GeForce 8800 GTS 320MB in terms of average speed.
That’s not surprising since the GeForce 8800 GT is slightly inferior to the GeForce 8800 GTS 320MB in one parameter only, namely in memory bandwidth, but surpasses it in the rest of the technical characteristics. The pre-overclocked version supplied by Leadtek is only really good at 1920x1440. Anyway, the average speed of over 60fps with slowdowns to 55-60fps will surely satisfy even a most demanding gamer.
BioShock doesn’t support FSAA when running in Windows Vista’s DirectX 10 environment. That’s why we benchmarked the cards without FSAA.
Both versions of the Nvidia GeForce 8800 GT – the ordinary and the pre-overclocked one – look superb in this test thanks to the 112 shader processors clocked at 1.5GHz and 1.7GHz, respectively. It is a question whether the GeForce 8800 GTS 320MB and the Radeon HD 2900 XT can be used for playing this game at 1920x1200, but the GeForce 8800 GT easily provides a high speed in that mode, especially in the Leadtek version that is always faster than 40fps.
At a recommended price of $259 the Nvidia GeForce 8800 GT leaves no chance to the ATI Radeon HD 2900 Pro and even beats the ATI Radeon HD 2900 XT!
