A massive demonic invasion has overwhelmed the Union Aerospace Corporations’ (UAC) Mars Research Facility leaving only chaos and horror in its wake. As one of the few survivors, you struggle with shock and fear as you fight your way to Hell and back, in an epic clash against pure evil.

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:

In Doom 3, although all cards start off with similar frame rates, they very quickly lose momentum and only the 6800Ultra manages to maintain a respectable 76.5 frames per second at 1600x1200.

Enabling Anisotropic Filtering and Anti Aliasing, the true performance of the GPUs shows up, even at the lowest resolution setting. You can see the difference between the XL and 6600GT has now grown to 10-15 fps. When we set the resolution to 1600x1200, the XL could still deliver an acceptable 30fps.
