why cant you play graphic intensive games online?

Question by abhinav: why cant you play graphic intensive games online?
Games like Crysis, Call Of Duty require powerful graphics, why cant they be hosted online with users connecting to play from anywhere. Isn’t it a logical extension of cloud computing, or are internet connections not fast enough yet?

The video data would have to be sent to the computer displaying the game (and for video games, 1080p (Blu-Ray quality) is considered pretty low). This requires an enormous amount of bandwidth (both for the client, and for the server (except the server has to multiple it by the number of clients).

Then you introduce lag by having to send all keystrokes and mouse movements all the way across the network rather then just to the local computer. This doesn’t help for games that require rapid reactions.
