Doom III is another game that can make good use of some special features of the GeForce 6 and 7 architectures and of the efficient OpenGL driver written by NVIDIA’s programmers. That’s why the RADEON X850 and X1800-based solutions are at the bottom again. Unlike in The Chronicles of Riddick, the ASUS Extreme N7800GTX TOP doesn’t profit much from its higher frequencies, at least in the “pure speed” mode. This gain is noticeable in the “eye candy” mode, but doesn’t exceed 10% even in 1600x1200 resolution.
The multiplayer d3dm4 map unveils a somewhat different picture: released from the single-player mode limitations, the graphics cards of the GeForce 7800 family can now show their best. The Extreme N7800GTX TOP is 7% faster than the reference card in 1280x1024 and 10-11% faster in 1600x1200. The gap grows wider in the “eye candy” mode since the higher, 1.35GHz memory frequency of the ASUS card contributes even more to its performance. The RADEON X1800 XT competes with the GeForce 6800 Ultra here and allows you to play this game with comfort in all resolutions.
