Crysis
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 achieve a compromise between image quality and speed.

The ASUS EN9600GT Top 512MB leaves the opposing Radeon HD 3870 far behind, but the frame rate is not high. The average speed doesn’t make it to 30fps and you won’t have smooth gameplay in Crysis, especially in scenes with lots of enemies, unless you lower the level of detail.
Enemy Territory: Quake Wars
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.

There is an interesting competition in Enemy Territory: Quake Wars. The EN9600GT Top 512MB wins the first display mode easily but is overtaken by its opponents in the higher display modes. It must have something to do with the MegaTexture technology because ATI’s solutions haven’t been good in OpenGL but (talking about the Radeon HD 3870) feature high mathematical performance as well as high memory bandwidth.
