Everything is hosted in the cloud these days, including an increasing number of games. Heck, you can even roll your own remote gaming server and tap into it with one of Nvidia's Shield devices. The trouble is, the latency inherent to most mobile Internet connections can taint the streaming experience with certain kinds of titles. Researchers at Microsoft, the University of Michigan, and the Siberian Federal University have developed a speculative system that seems to mitigate the damage, though.
 
Dubbed DeLorean, the system is claimed to compensate for up to 250 milliseconds of round-trip latency. Blind-test subjects reported "only minor differences in responsiveness" between streaming Doom 3 and Fable 3 on a 250-ms connection and one with "no latency." The findings are detailed in this research paper (PDF).

This is great news for people who use PC gaming services like Onlive, and have a slower internet connection with slow pings.
