Sapphire Radeon X800 XT - PCI Express
Doom 3 v1.1 - Single Player
From the moment Doom 3 was released, ATi has been tweaking their drivers and optimizing to get their performance up to a level more competitive with NVIDIA's. They have made up quite a lot of ground (and have made up a little more with the Catalyst 4.11 drivers that were released while working on this review), but ATi still has some work to do. When testing with our custom single player demo, the GeForce 6800 GT jumped way out in front of the Radeon X800 XTs in every configuration. But the margins of victory ranged from about 10% to about 19%, which are much smaller than the 50% margins we saw when Doom 3 was first introduced.
