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:

As the introductory logo display informs us while launching Doom3, Nvidia based cards perform better with this specific test. Notice the fps differences between the NVidia cards and the X850. At 1600X1200, the XFX reported 11fps more than the AOpen card.

With filtering enabled, at lower resolutions, the NVidia chipset based cards reported similar performance. We are pretty sure that you won't buy such an expensive card, just to play your favourite games at 800X600. So we moved straight to to higher resolutions of 1280X1024 and 1600X1200. The ASUS is always ahead but we are mostly interested in the XFX's performance in comparison with the AOpen's and Sapphire's. The XFX is 5fps faster than the AOpen at 1280X1024 and 18fps than the Sapphire, while at 1600X1200 only 5fps than the Aopen, but still faster, and 17fps than the Sapphire.
