Performance in First Person 3D Shooters
Battlefield 2 game was written with Shader Model 2.0 hardware in mind, it features per-pixel lighting, normal mapping, bloom as well as plethora of post-processing effects.
In low resolutions performance of all graphics cards is limited by the speed of central processing unit (CPU), however, in 1600x1200 the GeForce 7800 GT manages to demonstrate tangible advantage over the GeForce 6800 Ultra as well as ATI’s RADEON X850 XT Platinum Edition (PE).
The difference in speed of the GeForce 7800 GT and 7800 GTX is not really substantial with full-scene antialiasing and anisotropic filtering enabled. The former is definitely faster compared to the GeForce 6800 Ultra, but the RADEON X850 XT PE sometimes manages to leave the novelty behind, which is mostly due to very efficient FSAA patterns of the RADEON X8 as well as its high memory speed.
It is also very interesting to note that sometimes single GeForce 7800 GT is on par or even faster than two GeForce 6800 Ultra graphics cards in SLI mode.
