Far Cry 2
As opposed to Crysis, the GeForce GTX 460 SLI looks good compared to the Radeon HD 5970 in Far Cry 2 even at 2560x1600. There were no image quality problems or anything; the gameplay was smooth even in the most complex scenes. Well, Far Cry 2 is not a heavy application anymore.
Note also that the gap from the GeForce GTX 470 SLI is very small which means we are unlikely to see dual-GF100 cards (unless ASUS releases a limited edition of yet another unique monster), but a dual-GF104 card, especially with all of the 384 shader processors unlocked, is going to be a competitive solution.
This game is tested without multisampling antialiasing as it worsens the textures and provokes a performance hit.
The Radeon HD 5970 is in the lead in Metro 2033, especially at a resolution of 2560x1600, unless you turn on tessellation which wouldn’t be conspicuous in the dark post-apocalyptic underground tunnels anyway. Nvidia needs something better to match the speed of the AMD flagship, for example a dual-GF104 solution with both GPUs working in their maximum possible configuration.
S.T.A.L.K.E.R.: Call of Pripyat
We use the game’s DirectX 10.1 and DirectX 11 modes for graphics cards that support them.
At the two lower resolutions the tandem we are discussing cannot overtake the GeForce GTX 470 SLI, matching the latter’s performance, but then it falls behind suddenly at 2560x1600. The bottom speed is below 20 frames per second in that mode and the game is hardly playable. We don’t think this is due to its texture-mapping subsystem which is just as good as that of the GeForce GTX 470 SLI and even better since the GeForce GTX 460 SLI has a higher GPU frequency. And if the problem is in low performance of the computing subunits, the situation can only be improved by unlocking all the 384 ALUs of the GF104 chips. The Radeon HD 5970 doesn’t feel a lack of computing resources and performs very confidently at 2560x1600, making the game playable at that resolution.
