We know some people love to turn on all the eye candy possible. So, we tested
the card with Anti-Aliasing and Anisotropic Filtering on top of the Ultra
High Quality setting.
We see that with 4 x Anti-Aliasing and 8 x Anisotropic Filtering turned on,
the 512Mb card takes the lead at all resolutions. It gives a 2 to 4% edge over
the 256Mb card, but it does not make the game much more playable. At such
settings, only 1024 x 768 is playable and it does have its slowdowns during
intensive gun fights.
Finally, we tried Doom 3 with every possible eye candy turned on:
At this setting, even though the 512Mb card is about 1fps faster, none of the
resolutions used can be considered playable. At 1600 x 1200, it plays like a
slide show, not even hitting an average of 20fps.
- From our tests, the 512Mb card is not much better than the 256Mb. The
difference between the 2 cards even with all the eye candy turned on is barely
1fps, and I would consider that negligible.
- We tried tweaking the Doom 3
configuration file to try to improve the utilization of the extra graphic memory
but had no success. For this game, we feel that the 512Mb card does not offer
any advantage over the 256Mb card.
- With our 19"monitor, we could only feel
the image quality improve up till 1600 x 1200, 4xAA and 8xAF. Above this
setting, the dark environment of Doom 3 does not show significant image quality improvement.
