Perry said the games can run on less than a megabit a second of Internet bandwidth. Most DSL connections offer around three megabits a second, coming downstream into the home. In the demo, Perry said, the server was about 800 miles away, which results in a round trip (ping rate) of 21 milliseconds. That’s a split second and not really noticeable. For a server much closer, the ping rate is about 10 milliseconds. While both OnLive and Otoy used custom servers with graphics chips, Perry said his service can run across low-end custom servers.

Perry contends the ping rate is fast enough to play most games. He showed racing games such as Mario 64 and other games such as World of Warcraft and Eve Online, all playing without downloaded software. He also showed how he could use Adobe Photoshop across the server.
