Performance in First-Person 3D Shooters
Call of Duty: World at War
With the exception of the GeForce GTX 280, every graphics card included into this test session is so fast that they all reach the performance ceiling in this game. It is only at 2560x1600 that we have some data for comparison: the Radeon HD 4870 X2 proves to be slower than its new dual-chip opponent. It needs one more RV770 core for successful competition.
When we turn on extremely high levels of antialiasing, Nvidia’s solutions have an advantage in the way of the less resource-consuming 16xQ CSAA algorithm that needs 16 samples on the coverage grid but only 8 color samples whereas the 8x CFAA + Edge-detect Filter algorithm employed by ATI makes the GPU perform more work to filter the edges. As a result, the Radeon HD 4870 X2 has the worst result among the tested cards in this mode. Moreover, the extreme antialiasing modes can only be used at the resolution of 1280x1024 whereas the image quality improvements are barely perceptible.

We think that the minimum improvement in the smoothing out of small details is not worth such a terrible performance hit.
Nvidia’s new dual-chip flagship is ahead of its opponent at every resolution, being just a little slower than the bulky and hot tandem GeForce GTX 280 SLI. However, our apprehensions come true at 2560x1600 where 896 megabytes of local memory is not enough for the GeForce GTX 295. There is nothing bad about that loss, however, because the frame rates are low overall.
