Earlier this week, DICE delivered a new Xbox One X patch for Battlefield 1, bringing full 4K support to the 2-year-old World War I shooter. The tech heads at Digital Foundry have given the Xbox One X patch the once-over, and found that it does, for the most part, deliver a true 4K experience. Due to dynamic resolution scaling, Battlefield 1 can drop to as low as 3360×1890 on Xbox One X, but that’s still a step up from the PS4 Pro version and its checkerboard upscaling. Of course, the PC version is still the gold standard, but the Xbox One X patch seems like a solid offering…for most part.

Unfortunately, the Battlefield 1 Xbox update also seems to have introduced a nasty multiplayer bug. People trying to play Battlefield 1 while in an Xbox Live Party are experiencing serious performance issues. Digital Foundry experienced framerate drops of around 10fps and severe stuttering, with frame-time spikes of up to 133ms, or around 8 frames. These issues are affecting Battlefield 1 on both the standard Xbox One and Xbox One X, with the issues being particularly bad on the base model.
