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:

You can easily tell the N6600GT is an NVidia card just by looking at the chart above. Its performance easily exceeds that of the Sapphire X800 and climbs up to reach the X800XL. Once again, high resolution and Anti-Aliasing/Anisotropic Filtering is the only solution for the ATi cards.

Now the 6600GT's performance has obviously dropped and it can no longer do as well as the X800XL. Moreover, the difference between it and the Sapphire X800 is slowly declining to zero as we move to the higher resolutions.
