PlayerUnknown's Battlegrounds is one of the Xbox One's biggest launches of the holiday season. But now that the game is out on the console, it turns out that it's a bit rough right now. Recently, Digital Foundry did an in-depth breakdown of the Xbox One and Xbox One X versions of the game, and it showed that they've got a long way to go before they're in line with the PC version.

It's not exactly surprising that the game doesn't perform as well on the base Xbox One, since porting a PC-first game like PUBG to a relatively weak platform is a difficult task. In addition, it's currently in Early Access, so it's expected to be less polished. As Digital Foundry notes, when you join a game, "You're instantly besieged by low resolution textures that seem to be failing to stream in properly, combined with performance just above or below the 20fps threshold."
