Mass Effect Andromeda, the last entry in the sci-fi IP created by BioWare, just got enhanced for the Xbox One X console. There has been no official announcement yet, but the Microsoft Store and the official Xbox One X enhanced list both mention it now and several users have already received the Update (1.68GB in size). The 4K/Ultra HD tag isn’t there, suggesting that the game does not reach native 4K resolution.

For reference, Mass Effect Andromeda runs at 1800p resolution through checkerboard rendering on PlayStation 4 Pro hardware. If we had to bet, we’d guess that Andromeda can run at native 1800p resolution on Xbox One X with no need for checkerboard rendering.
