Activision made it's miracle again with Doom 3 which is said to be the best-looking game ever, thanks to the brand-new OpenGL graphics engine used to generate its convincingly lifelike, densely atmospheric, and surprisingly expansive environments. If you are a fan of the previous Doom games then you will get many flashbacks with this revision, since you will find reimagined versions of almost every monster from both Doom and Doom II.

To measure performance on the game we used the timedemo demo1 command from the console (Alt+Ctrl+~).
Enabling the high quality setting and executing the timedemo demo1 command twice for each resolution, we witnessed the following:

First, without the Anti-Aliasing and Anisotropic Filtering settings enabled, we got the following results:

There are two things that should be pointed out with Doom3. First of all, the game "prefers" nVidia cards, and this is why we got such low framerates at higher resolutions with the Sapphire X850XT card. The second thing that should be pointed out is that the game itself can only provide a maximum of 110fps in the demo run. This means the we have reached the game limits with the nVidia cards and this is why all nVidia based cards reported similar performance at all resolutions.

With 4x Anti-Aliasing and 8x Anisotropic Filtering settings enabled, it is easier to see how the two 7800GTX cards stand apart from the others, since they managed to go as high as 89fps at 1600x1200, while the ASUS N7800GTX TOP that came second, managed to get 60fps at the same resolution.
