Performance in First-Person 3D Shooters
The Radeon X1650 XT beats the GeForce 7600 GT in our first test, but can’t match the GeForce 7900 GS that boasts 20 TMUs, 16 ROPs and a 256-bit memory interface. The gap isn’t bigger than 10-13%, though.
It should be noted that the graphics card is fast enough only at 1280x1024 without full-screen antialiasing, and even in this case its average frame rate is lower than the 60 frames per second which you need to play a first-person shooter with comfort.
Call of Duty 2
Although the game employs a new renderer with support for cutting-edge shader-based DirectX 9 effects, its engine is a modified version of the Quake 3 engine. This is perhaps the reason why the AMD cards are so slow: the Radeon X1650 XT is everywhere slower than the GeForce 7600 GT while the Radeon X1950 Pro, having more pixel processors and a higher core frequency, cannot surpass the GeForce 7900 GS.
The game is obviously too demanding for graphics cards like Radeon X1650 XT and GeForce 7600 GT, and you can’t get a comfortable speed from them even by disabling full-screen antialiasing. You’ll probably have to switch to 1024x768 or use lower graphics quality settings.
