The promised current-gen upgrade for Fallout 4 won't be released until sometime in 2024.

Bethesda has announced this. The upgrade was initially planned for release this year. “Thank you for your patience as we work on the upgrade for Fallout 4. We know you’re looking forward to it – so are we! But we need a little more time and look forward to a return to the Commonwealth in 2024.”

The upgrade was announced last year in conjunction with the franchise’s twenty-fifth anniversary. This is a free upgrade for current owners of the game and will be available on PC, Xbox Series and PlayStation 5.

The upgrade will add performance mode options, higher frame rates and support for 4K resolution. Various bugs also need to be fixed and it contains more content for the Creation Club.
