The Radeon X1650 XT is successfully competing with the GeForce 7600 GT throughout this test. The more advanced memory controller gives an advantage to the AMD solution in high resolutions of the 4x FSAA + 16x Aniso mode.
The resolution of 1600x1200 pixels plus 16x anisotropic filtering is the highest playable mode for both graphics cards. They aren’t strong enough to perform full-screen antialiasing even in such an undemanding game as Far Cry (well, you can try to enable 4x FSAA at 1280x1024, but don’t complain about occasional slowdowns).
The Radeon X1650 XT feels much more confident on the Research map in the FSAA mode than in the previous case, enjoying an advantage of 20% over the GeForce 7600 GT. The graphics cards deliver higher speeds in this test on average, but it is still arguable whether FSAA is an option. The speed may bottom out below comfortable level as soon as you go out into an open scene.
The numbers suggest that the FP HDR mode of this game is totally unplayable on graphics cards like Radeon X1650 XT or GeForce 7600 GT. The speed is too low.
