Call of Duty 2
Call of Duty produces a different picture of performance than the one we’ve seen in Battlefield 2. The EN7800 GT Top Silent is better than the reference card in resolutions lower than 1600x1200. This is rather strange since the memory frequency should have had a very small effect on the overall performance then. Anyway, the resolution of 1024x768 is the only one in which you can play at a comfortable speed and with enabled FSAA on the tested cards, except for the Radeon X1800 XT which delivers 50fps in 1280x1024, too.
The EN7800GT Top Silent falls the father behind the GeForce 7900 GT as the display resolution grows, which is normal considering the better specs of the latter. Like in Call of Duty, the performance of the ASUS and of the standard GeForce 7800 GT coincides in 1600x1200 despite the hefty advantage in memory frequency the ASUS has.
Despite the game’s OpenGL-based engine and some GeForce 6/7-oriented rendering techniques, the Radeon X1800 XT is always in the lead in the standard resolutions, although the GeForce 7900 GT follows it closely in 1600x1200. The resolution of 1280x1024 seems to be the highest comfortably playable on any card, except the Radeon X1800 XL.
