PUBG is finally coming to Xbox One in December. On Xbox One X, you can expect the Hunger Games-style shooter to run at 60 FPS, creator Brendan Greene said in a new interview. But on the standard Xbox One, which has less power, the frame rate could be halved.

"Definitely on Xbox One X, 60 FPS," Greene said in the latest issue of GamesTM, as reported by Wccftech. "On [the standard] Xbox One, we're not sure. We may have to limit it at 30 FPS, maybe, but the last time I saw it, it was running at about 30 to 40."
