by Mikhail Madnani on 26 March, 2026

Fallout 4: Anniversary Edition for Nintendo Switch 2 has gotten its newest update today bringing in support for DLSS and more.

Bethesda has also revealed the patch notes confirming that DLSS will be available in the 40fps and 60fps modes to improve image quality. DLSS will not be engaged for UI-heavy scenes like the Pip-Boy and more to ensure text is sharp. Read my early impressions with the port before today's update here. 

Fallout 4: Anniversary Edition is available for Switch 2, PS5, PS4, Xbox, and PC, featuring the base game, six add-ons, over 150 pieces of Creation Club content, and more.
