Where in the office the team were playing on live servers with game running at about 30 - 40 fps. No word on resolution or optimisation for the Xbox One version of PlayerUnknown’s Battlegrounds, but this is the sort of thing that apparently is quite easy to implement. With Xbox One X representing power equivalent to a decent PC rig.
Speaking with Eurogamer, Brendan "PlayerUnknown" Greene stated the following.
We have a version running on the Xbox One X prototype in the office which can plug into the online servers. We were playing on live servers on the console at about 30 or 40 FPS. So it works on 100 man servers.
Adding that a small team in Spain is currently working on the console version of PUBG. No word yet on an Xbox One release date, but with the Xbox One X due in November, we should probably expect a release somewhere around that time.
