The Elder Scrolls IV: Oblivion
This game was not tested in FSAA modes since HDR support is disabled even on ATI’s graphics card in that case and the quality of graphics degenerates noticeably. It is also impossible to turn on the Bloom effect alongside with HDR. TES IV: Oblivion lacks any benchmarking options so we had to use Fraps and test manually, so the numbers may be somewhat imprecise.
The graphics card is required to process lighting and shadows in the Oblivion dungeons. More pixel processors are welcome due to numerous pixel shaders. The GeForce 7900 GT has the most pixel processors of all and this show in 1280x1024 and higher resolutions. In 1024x768 the cards are all similar, except for the slow Radeon X1800 XL.
Considering that Oblivion is not all about dungeons, we recommend using 1024x768 resolution with graphics cards of this class especially if you enable the HDR mode.
The GeForce 7900 GT enjoys a colossal advantage over the other cards in open scenes, although we can’t say it delivers a comfortable average performance. The ASUS EN7800GT Top Silent has a lower min frame rate in 1024x768 than the Radeon X1800 XL, while the GeForce 7900 GT is slower than the Radeon X1800 XT.
It means that R520-based solutions are preferable to same-class G70- or G71-based cards in Oblivion.
