The Radeon X1900 XTX from ASUS provides a frame rate of over 90fps in 1600x1200 with enabled full-screen antialiasing and anisotropic filtering, leaving the rest of the graphics cards behind in this test. Well, the participating devices all show satisfactory speeds, except for the GeForce 7900 GT which is slower due to its low memory and GPU clock rates.
Pixel shaders are used on the Research map to process the lighting model with many light sources, so it is logical that a high frequency and large number of pixel processors make a difference in the rendering speed for this scene. The graphics cards all deliver comfortable speeds here, though.
The ASUS EAX1900XTX is still in the lead, but the GeForce 7900 GTX is successfully competing with the Radeon X1900 XT. The slow GeForce 7900 GT now runs along with the Radeon X1800 XT which has 16 pixel processors, too.
The HDR support for ATI’s Radeon X1000 cards still has a beta status in the current version of Far Cry, but the performance of the ASUS EAX1900XTX is rather high in this mode and allows using 1280x1024 resolution. Unfortunately, Far Cry’s implementation of HDR is not efficient when it comes to the Radeon X1000 architecture.
The same thing can be observed on the Research level. The difference in the GPU frequency being a mere 25MHz, we are not sure why there is a 20% difference in speed between the Radeon X1900 XT and the ASUS EAX1900XTX.
