Perhaps you’ve heard of an old technology called VNC, or Remote Desktop, or PC Anywhere. These are all remote control technologies that have been around for years; you sit at a keyboard and mouse somewhere, and when you move the mouse or type, the signals are sent over a network to a computer elsewhere. The computer, in turn, sends constant screenshots of itself back to you, so it is as if you are sitting at that computer even though you’re in a room in another part of the building, or the world.
The problem with VNC has always been lag. It takes time for your computer to say “I moved the mouse up one pixel”, send that across various network links to the other machine, for the other machine to process it, and then send back an entire re-draw of the screen with the mouse cursor now moved one pixel up. Through compression technologies and other advances in processing and network speed, the process has been made pretty seamless over the years, but there is still a slight feeling of “oddness”— you can still tell you’re not sitting at that actual computer. Over an internal network link (you’re in the same building) it is really good, but over the internet, performance is still sketchy, even in 2009.
Therefore it is with skepticism that we read the news all over the web today about a new company called OnLive who is making big claims about being able to provide this service for PC gaming. Yes, they fully intend to deliver remote control gaming to end users for the fraction of a cost of buying a decent gaming PC and software to go with it. You get a controller, a little box to hook up to a display and a network, and then you pay to play any of the top games that are out. Apparently OnLive has the hardware to push these games in real time over an internet link.
There are limits; high speed remote gaming can only occur over exceptionally low-latency links. They are rolling out datacenters in urban American markets and are saying that gamers “within 1000 miles” of those datacenters will be able to have the full OnLive experience. Tentative figures state that 480p gaming can only occur with 1.5mb connections and 720p gaming requires 5mb. Pricing and subscription model have not been revealed yet. Beta testing begins this summer.
