NVIDIA’s cards keep their superiority on the Recycling level, too.
The RADEON X800 XT performs somewhat more confident in the eye candy mode, but makes no sensations.
Once again, Doom 3 shows its fancy towards NVIDIA’s GPUs: new and old GeForces are the best in their classes.
It is all the same as on the previous maps: the RADEON X800 XT is better than the GeForce 6800, but the GeForce 6800 Ultra/GT are still unattainable.
Like in the High Quality mode, NVIDIA’s graphics processors are better than RADEONs with the Medium Quality settings. Only with full-screen antialiasing and anisotropic filtering enabled, the RADEON X800 XT Platinum Edition could outperform the much cheaper GeForce 6800. The same situation is in the eight pipelines sector: the GeForce FX 5950 Ultra is preferable to the RADEON 9800 XT, which delivers the performance of the GeForce FX 5900, roughly.
Note also that the requirement to have 256MB of graphics memory is superfluous for mainstream cards: you can’t enable FSAA in high resolutions on such products, while 128MB is quite enough for typical loads.
