Last week there was some measure of shock in the Xbox community when it was discovered that thanks to its 4K assets, the download for upcoming racer Forza Motorsport 7 will weigh in at around 100GB.

However, Microsoft has told Aussie site Stevivor that only the Xbox One X will download the game's 4K assets, so the bandwidth of Xbox One and Xbox One S owners will be somewhat spared.

“With the launch of Xbox One X, when it comes to game content our intention is to download the correct assets to the correct console,” a Microsoft representative told Stevivor.

“This means, regardless of the TV you are playing on, 4K assets will be downloaded to Xbox One X (if available) and the standard 1080p assets will be downloaded to a Xbox One S.”

Those who buy an Xbox One X but don't have a 4K display will still benefit from 4K assets thanks to supersampling, a process that downsizes 4K assets to HD, removing rough edges ("jaggies") in the process. This means it's unlikely Microsoft will allow Xbox One X owners to opt out of 4K asset downloads.

The Xbox One S features 4K Blu-ray, and 4K video streaming, but it isn't capable of processing 4K assets. Instead, for those with 4K displays, it upscales 1080p games to "4K". It therefore doesn't require 4K assets.

Microsoft said it has deployed a tool to developers that will allow them to choose what gets installed on players' consoles.

“In addition to 4K specific assets, developers have options when it comes to language specific assets as well, which depending on the title, can drastically reduce the install footprint," the spokesperson said.

"This ability to intelligently install the best assets for each console and language are available on all Xbox One devices, and it will be up to the developer of the game to determine the specific implementation.”

Microsoft promised to share more on this feature in the coming months.
