It’s only in 1280x1024 resolution of the “eye candy” mode that we can see some difference between the participating graphics cards. The Sapphire RADEON X1800 XL turns in a brilliant result here, going abreast to the 24-pipelined GeForce 7800 GTX and leaving the immediate rival GeForce 7800 GT far behind.
The Sapphire card finds the Research map with its per-pixel lighting a more difficult trial. According to theoretical tests, the employed shaders are executed much faster on the GeForce 7800 GTX than on the RADEON X1800 XL. Moreover, even though the RADEON X1000 architecture is oriented at efficient execution of version 3.0 shader code, it shows its real best only on the most complex shaders or on shaders that use dynamic branching (such are missing in Far Cry ). These are the reasons for the Sapphire RADEON X1800 XL to be slower than the GeForce 7800 GTX here (and even than the GeForce 7800 GT in the “pure speed” mode). But anyway, the Sapphire always ensures a playable frame rate in Far Cry , so you won’t have the excuse of a sudden slowdown for your poor aiming!
