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:

With the first few resolutions in Doom3, the Extreme N6600GT card is burdened by the lack of CPU might, being unable to unleash its full power. When that bottleneck is no longer an issue, it's obvious the X800 cannot compete with it and gets easily outperformed.

Enabling 4xAA and 8xAF, the N6600GT receives a serious performance jolt, which gives the X800 the opportunity to narrow the difference further each time we increase the resolution.
