OnLive's latency has again come under scrutiny, with gamers concerned that network delays might scupper the immediacy of their play. DigitalFoundry hooked up a Ben Heck latency monitor with an Xbox 360 joypad and then filmed some gameplay with a 60fps camera; slowed down and frames counted, they figures out that the OnLive system could manage an optimum response of 150ms.
Now, that's significantly more than the 34-40ms that OnLive themselves suggested gamers would usually see, but still roughly on a par with playing Killzone 2 locally. It's also important to factor in the condition of your network, too: your broadband speed could make a big difference (OnLive say 5mbps or higher is ideal) and individual games also fluctuate. DigitalFoundry found Unreal Tournament III was relatively stable at 150ms, while DiRT 2 and Assassin's Creed II both showed significant ranges, of 167ms-200ms and 150ms-216ms respectively.
