This game is tested at the High level of detail, excepting the Shaders option which is set at Very High This way we try to strike a balance between image quality and speed.
ATI’s tandem equals the GeForce GTX 280 at 1600x1200 and surpasses it at 1920x1200 but has a lower bottom speed in comparison with the single card. Nvidia’s solution is on the winning side but its performance is barely acceptable at 1280x1024 as the bottom speed is lower than 25fps.
The game obviously needs more than 512 megabytes of memory to run at 2560x1600 pixels. Thus, it runs on the GeForce GTX 200 series only.

The frame rate is fixed at 30fps in this game as this is the rate at which the physical model is being updated at the server. Thus, this 30fps speed is the required minimum for playing the game.
CrossFire technology shows low efficiency. The Radeon HD 4850 CrossFire configuration has the same performance at 2560x1600 as the single Radeon HD 4870. This is about 16% slower than the speed of the GeForce GTX 260 and equal to the result of the GeForce GTX 260. From a practical point of view, the average frame rate is high enough for playing the game at the highest resolution together with 4x MSAA.
