Performance in Third-Person 3D Shooters
This game doesn’t support display resolutions of 16:10 format, so we use a resolution of 1920x1440 pixels (4:3 format) instead of 1920x1200 for it.
The Zotac does not benefit much from the pre-overclocked frequencies, being about as fast as the ordinary GeForce 9800 GTX. The biggest difference between them is only 1.9fps, which is negligible compared with the average frame rates of 80-90fps. The ATI Radeon HD 3870 X2 is no worse for practical purposes but its minimum speed is lower and it consumes considerably more power.
BioShock doesn’t support FSAA when running in Windows Vista’s DirectX 10 environment. We benchmark graphics cards without FSAA in this game.
Both versions of GeForce 9800 GTX reach the performance ceiling set by the other testbed components, particularly by the CPU, at 1280x1024. The Zotac goes ahead of the reference card as the resolution grows up. The gap amounts to 7% at 1920x1200 and the Zotac is formally faster than the Radeon HD 3870 X2. The latter shows a higher minimum of speed, though.
