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:

The Asus N6600GT has what it takes to render Doom3's demanding scenes and this fact was widely publicized by NVidia when it introduced the model onto the market. With the framerate being around 60fps at 1280x1024 resolution, the Asus N6600GT is an excellent choice if you're a Doom fan.

When we set AA to 4x and AF to 8x, the X800's much larger fill rate comes into play. Comparing the two graphs above, you'll notice that the card's performance only drops by 16% to 40% while the two 6600GTs drop by 40% to 60%.
