After some tests, PCGH claims you don’t need a high-end rig to run Far Cry 2 at decent framerates, even with the ultra-high settings. Far Cry 2 is a Direct3D game (Dx9 under XP and DX10 under Vista). The tests have been done in 1680×1050 and the testbed includes an Intel QX9650, 4Gb-DDR3-1333-RAM. Graphics cards used in the high-end GPU test were the GeForce GTX 260 Core 216 SLI and Radeon HD 4870 X2 and average framerate was around 60 FPS (no MSAA) for both cards. Middle-class GPU benchmarks included GeForce 9800 GTX+ and Radeon HD 4850 and average framerate was around 40 FPS (no MSAA). When MSAA is set to 4 samples, the Radeon HD 4850 gets a better score than the GeForce 9800 GTX+.
Modern graphics cards are so powerful that new games are not capable to flood them with enough pixels (as long the GPU is supported by a powerful CPU). And the test doesn’t include the GeForce GTX 280. A little stability and rest for 3D graphics developers!
