“The absolute fastest card we've seen for Doom 3 has been the 6800 Ultra series of cards.”

“Let’s face it; it’s the GPU in your computer that’ll make the single largest impact on Doom 3’s ability to run good frame-rates for your gaming pleasure… NVIDIA is clearly the better solution for Doom 3.”

Gamespy
“I've been playing on a P4 3.0 Ghz machine with 1GB RAM and a GeForce FX 5950, and at a resolution of 1024x768, my framerates have been rock solid, usually sticking between 40-60 FPS. Even with antialiasing turned up to 4x, my framerate only dipped down 10-12 frames a second, and was still more than playable.”

“We're running the game itself at the "ultra" graphics setting at 1024x768 resolution with 4x antialiasing and all the trimmings and have been experiencing silky-smooth frame rates…”

PC Gamer
“Not surprisingly, you’ll need a monster system to render these monsters in all their intricately textured glory. But the ability to play Doom 3 with all it’s visual magic maxed-out is a really good excuse to trade up. A P4 3GHz with a GeForce 5950-class card will see you through okay. One of our test systems had a GeForce 6800 and ran flawlessly at 1024x768 resolution with high detail (a higher level of quality and resolution is available, but the PC to run it well isn’t!). Even running with a GeForce4MX card and 512MB RAM, the texture detail was great, although the game was noticeably choppier in some spots. Bottom line: If Far Cry didn’t convince you, then Doom 3 should – the time to upgrade to a next-generation 3D chip, or even an all-new rig, is now.”

Doom 3 Technical:

Time Magazine
“At first glance at a computer screen running Doom 3 is confusing to the eye: the illusion the game creates is so realistic. The secret? Light.”

USA Today
“The action in Doom 3 promises to be more intense than its predecessors, with effects and environments reminiscent of such movies as Alien, thanks to Carmack's breakthrough method of realistically tying lighting and textures of objects to the player's movements.”

USA Today
“The new game is more realistic — and intense. Says id Software technical director John Carmack: “We can rely on more subtle levels of light and create moods, film director-style.’”

Seattle Post-Intelligencer
“The dynamic lighting in "Doom 3" behaves like real-world lighting. Rather than setting gamma levels, id's designers lit the rooms of their Martian laboratory the same way they would light their own homes, one fixture at a time. All lighting in "Doom 3" comes from in-game sources. Walk into a room, shoot out the lights and you will find yourself in the dark.”

Detroit Free Press
“Doom 3 will retain the familiar style, with technological advances to make it more consuming . Dynamic lighting, a haunting score and a brand-new graphics engine may set new PC gaming standards.”

Associated Press
“With each release, the visuals, sound and other effects have improved. "Doom 3" is by far the most realistic and looks nearly equal to animated films like "Shrek 2."

Gamespy
“It doesn't take more than two minutes to see how advanced DOOM 3's new graphics tech is.”

Gamespy
“From a technical perspective, there's no way around it: DOOM 3 is a sight to behold in motion. The shadows and lighting create an amazingly creepy setting, and give the character models a unique look.”
