The designers ..... some are both.... that is a game may be limited by GFX card in single player mode but limited by CPU in multi player mode.
I guess I mean... Which 'Aspects' of a game effect it.
Large environments, high polygon count models, large number of models, real time physics simulations all put increased stress on the CPU. Some games such as these are very well optimized for multi-threading, some are not. This is what makes all the difference in the end whether a game will be CPU based or not.
