Bethesda has rolled out a major update for Fallout 4 on Nintendo Switch 2, breathing new life into the classic post-apocalyptic RPG on Nintendo’s latest hybrid console.
The headline feature of this update is official NVIDIA DLSS support for Switch 2, which unlocks two high-performance modes: 40fps and 60fps. Using AI-powered upscaling, DLSS preserves visual quality while drastically boosting frame rates for smoother wasteland exploration on Switch 2.
A thoughtful detail from the developers: DLSS automatically disables in UI-heavy scenes (such as the Pip-Boy menu) to keep text sharp and readable.
Full Patch Details for Fallout 4 Switch 2
Beyond performance upgrades, the update fixes dozens of gameplay‑breaking issues on Nintendo Switch 2:
- Resolves multiple crash bugs, including save file crashes, main quest crashes, and crashes when docking/undocking the Switch 2 console
- Fixes missing button prompts in trade menus and incorrect HUD settings
- Improves overall save system stability
- Corrects missing or broken text for Japanese and Traditional Chinese
While the Switch 2 delivers a big performance leap over the original Nintendo Switch, it still trails behind flagship consoles like the PS5. DLSS technology has become a key solution to close this gap for Switch 2 players.
Sources confirm Nintendo plans to upgrade the Switch 2 DLSS version in Spring 2026, which will introduce AI frame generation for the first time. This upgrade will help bring more AAA blockbusters to the Switch 2 platform.
For Switch 2 owners, the addition of DLSS makes the nearly decade-old Fallout 4 feel fresh again, delivering a far more immersive adventure across the Boston Wasteland.
As DLSS becomes more widespread on Nintendo Switch 2, players can expect smoother performance from even more big-budget AAA games coming to the console.
