The authors of Borderlands 4 presented another patch in early October. They updated the weekly boss and Wildcard activity, and also made a number of changes.
Automatic cleaning of outdated Borderlands 4 shaders was added to the game when the version is updated, which "prevents performance degradation on some PCs."
They also made balance adjustments to the Vault Hunters: Harlow was almost not affected, while Raf, Vex, and Amon received many ability enhancements.
For example, for Vex, the damage of active skills was increased: Phase Explosion by 16.6%, and Eldritch Blast by 9.5%; passives were also enhanced.
