Visual comparison between COD and other upcoming releases

[recoilfx]

Map size shouldn't affect performance much if the game is properly engineered.

Beyond what the player can't see the game shouldn't be wasting calculations on them (IE, skip rendering, simple flight modeling/dm/ai).

The amount of object details rendered will have more of an impact. In the case of CloD, it seems to have the biggest problem loading assets that cause stutters and slow fps with particles effects.
