A game-changing free mod brings AMD FSR 3 frame generation to Fallout 4, offering up to 2x performance gains in demanding scenarios. Created by doodlum—the developer behind Skyrim’s Community Shaders—this mod provides a no-cost alternative to paywalled solutions, making smooth gameplay accessible to all DirectX 12-capable GPU owners.
FSR 3 Frame Generation Performance
| Scenario | Improvement | Best Use Case |
|---|---|---|
| City Areas | Up to 2x FPS | High NPC density zones |
| Modded Builds | Significant boost | Sim Settlements 2 users |
| Base Game | Smooth framing | 120Hz+ displays |
How the Mod Works
The mod utilizes AMD FidelityFX Super Resolution 3 technology through a custom DirectX 12 swap chain proxy, making it compatible with any DX12-capable graphics card—including NVIDIA and Intel GPUs. This universal compatibility sets it apart from vendor-locked solutions.
By default, frame generation activates only on displays with 120Hz or higher refresh rates, though users can force-enable it via the configuration file. The technology shines brightest in CPU-intensive areas where traditional optimization struggles, such as downtown Boston or heavily modded settlements.
Installation Requirements
The mod requires several prerequisites: Address Library for F4SE Plugins, High FPS Physics Fix, and running Fallout 4 in Borderless or Windowed mode. It plays nicely with ENB and PureDark’s free upscaler mod (when set to DLAA or native AA), though VR users should note it’s incompatible with Fallout 4 VR.
Released as part of the Fallout 2025 Modathon on Nexus Mods, this represents doodlum’s second contribution to the competition running until December 31, 2025. The timing coincides with Fallout 4’s tenth anniversary and the controversial Anniversary Edition launch that broke numerous existing mods.
