Bethesda explains that Fallout 4’s Far Harbor add-on—having just launched over the weekend on May 19—was released once improvements had been made on its beta version, which had its contents leaked by testers prior to availability. Regarding the fixes currently taking place, the developer’s statement in full on its website is as follows:

Some of the issues that fans of Fallout 4’s Far Harbor may be encountering could stem from frame rate and general performance problems, as a lot of players have reported that there are dips below 20 FPS when on a sizable portion of the DLC’s new landmass. It seems as if the majority of the slowdown and glitches are occurring due to the expansion’s radioactive fog, which is unique to the add-on. However, with the airborne haze being a main component of Far Harbor, developers will have to find a workaround by way of lighting and atmospheric effects instead of removing the feature completely.

“Thank you for playing Fallout 4.”

For those unaware, Far Harbor is Fallout 4’s third paid expansion pack thus far, which can be obtained for $25 as a standalone, or they can receive it for $50 in the game’s Season Pass. Should fans purchase it in a bundle with the other add-ons, they will also receive everything else released thus far, including the excellent Automatron DLC and Wasteland Workshop. Not to mention, there ought to be even more to come in the future, as Fallout 4’s director, Todd Howard, has promised players the open world title is set to have downloadable content that will release “well into” 2016.

In the meantime, while Bethesda hammers out the problems to Fallout 4’s Far Harbor DLC, fans can still play through the 20-plus hours of content, but they risk coming across some graphical hangups. Of course, should some Wastelanders wish to wait until all of the issues for the expansion are resolved, the post-apocalyptic RPG’s Survival Mode is always on standby, ready to give players an extreme challenge.

Fallout 4 and its most recent expansion, Far Harbor, are both out now and available for PC, PlayStation 4, and Xbox One.
