The headline feature of the patch is support for NVIDIA DLSS, which enhances image quality while maintaining stable performance in both 40 FPS and 60 FPS modes.

Beyond that, the update fixes a range of technical issues — including crashes, memory handling, and visual glitches. Lighting problems, flickering environments, and missing effects like textures or bullet marks have also been addressed.

Bethesda additionally refined the interface, resolving issues with menu transparency and incorrect button prompts.

Overall, this patch makes the Switch 2 version of Fallout 4 more stable, visually polished, and better optimized for portable play.
