Following a recent update to Borderlands 4, the main executable file, Borderlands4.exe, has decreased in size by approximately 171.69 MB. This change often accompanies the removal of Denuvo-related components, leading players to suspect that Gearbox Software has abandoned Denuvo anti-piracy protection for the title.
However, the available information is not yet sufficient to fully confirm this assessment. The Borderlands 4 Steam store page still lists Denuvo as a third-party digital rights management technology, meaning the page labeling does not corroborate the changes to the executable file.
Gearbox Software has not issued any official announcements or patch notes, and there is a lack of other materials that could directly confirm the removal. The store page has not been updated either, so it is currently only speculated that Denuvo encryption may have been removed.
