Performance in Strategy Games
Age of Empires 3
The drop in the Radeon X1800 XT’s performance is due to the game’s using shaders that cannot be executed quickly enough on 16 pixel processors. In 1280x1024 the ASUS EAX1900XTX is 15% faster than the GeForce 7900 GTX.
Note that both the flagship graphics solutions are capable of running this game fast in 1600x1200 with enabled FSAA and anisotropic filtering.
Warhammer 40000: Dawn of War
The graphics cards must have a high scene fill-rate and be fast at rendering stencil shadows to succeed in this test. The engine of Dawn of War obviously prefers Nvidia’s GeForce 7 graphics cards. Here, the ASUS EAX1900XTX is no rival even to the cheaper GeForce 7900 GT, not to mention the GeForce 7900 GTX.
Although the ASUS card provides an acceptable average performance in all the resolutions, you should be aware that its speed may bottom out to below 20fps. This has a negative effect on playability, of course.
