I'll leave this here, my prediction is that Stadia will be a similar experience:
"In examining latency, Eurogamer's Digital Foundry initial test found that in some of their test scenarios, users of OnLive could expect 150ms of latency over a consumer Internet connection; however, they also noted inconsistencies, in that some games had higher latency, and that this would also depend on the quality of the customer's internet connection. Furthermore, they also noted that while acceptable, these values ran contrary to figures suggested by OnLive before release of lag "being under 80ms" and "usually... between 35-40ms". In their later full-feature article on OnLive, Digital Foundry noted that "during intense gameplay, OnLive is hovering right at the boundary of what is acceptable lag and often exceeds it, resulting in a variable, often unsatisfactory experience", but that "the latency level is probably the most pleasant surprise with this system. Let's be clear: it is most definitely not a replacement for the local experience, but if the system can be tightened up and that 150ms becomes the norm, then it's clear there is potential here for the infrastructure to find a home with certain types of game or certain types of player".
In terms of video quality, Digital Foundry noted that video compression meant image quality also varied depending on the title. Games with a lower number of frame-to-frame differences, or games where such changes were less important, such as Assassin's Creed II or Batman: Arkham Asylum fared well, with these games being "strongly suited to video compression" and "cut-scenes in particular can look very good". However, games that had a greater amount of motion or relied on fast reactions, such as Colin McRae: Dirt, Dirt 3 or Unreal Tournament 3 fared less well, with questions about the playability of the latter when video compression artifacts were taken into account. Digital Foundry felt that the quality of rendering was mostly good, with high frame rates, but with less consistency than console counterparts and with screen-tearing in some scenarios.
Gaming Examiner judged that the graphics were like "playing a PlayStation 3 on a 480p standard [definition] TV", that they thought that they experienced much lower framerates than expected, and that the controller was not working reliably.
After the launch in United Kingdom, Computer and Video Games remarked that, after one month of use, the service was "working" and was adequate for trying or renting a game, but that it was not a substitute for owning a game on another platform due to the limitations imposed by internet connections (lag, freezing and smeary visuals, as well as high data usage for those on capped connections)."
For the supporters of this I hope I'm wrong. But I was sceptical before OnLive launched and in that case I was proven right and as I said Stadia will be simmilar.
