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 re-imagined 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:

nVidia 's cards are known to have better performance than ATI based cards with Doom3. Double the cards, double the performance... as simple as that. In SLI mode, fps values just couldn't drop below 100!

Anisotropic filtering and Anti-Aliasing give the ATI card a chance to show its worth. But again, the two nVidia flagships are far higher than the competition. I personally think that ATI's engineers decided to release CrossFire after looking at similar figures.
