Fallout: New Vegas gets recompilation for Mac; author reports 84 FPS average

Fallout New Vegas Mac received a public recompilation project for Apple Silicon on October 14, 2026. According to the person responsible for the thetheoryofR/Fallout-NV-MacOS repository, the RPG already runs natively on macOS and reached an average of 84 FPS in a test session by the author himself. However, the project still lacks audio and requires technical preparation.

Fallout New Vegas Mac uses recompilation for Apple Silicon

First, the tool translates the 32-bit Windows executable into code that can be compiled for Apple's ARM64 processors. In addition, a compatibility layer handles system calls and converts Direct3D 9 to Metal.

Thus, the proposal dispenses with Wine and CrossOver in this execution path. However, the author maintains the Unicorn interpreter as a support resource for sections that the analysis could not translate. Therefore, it is not correct to promise that the project has eliminated all forms of interpretation.

What the Fallout New Vegas Mac test showed

According to the README, one hour of automated traversal crossed 13 world cells, starting in Goodsprings, without crashes. In this test, the average was 84 FPS at 3456×1944 resolution.

Furthermore, the author reports at least 60 FPS about 96% of the time. However, the heavier areas dropped to the 53 to 59 FPS range. These numbers describe the scenario reported by the developer; they do not constitute an independent benchmark nor a guarantee for any Mac.

Audio and controls are still incomplete

For now, the DirectSound implementation remains silent. Additionally, the person responsible lists Bink video, gamepad support, parts of the graphics pipeline, and NVSE-dependent mods among the features still missing.

Therefore, running an exploration sequence is not equivalent to completing the adaptation of the entire campaign. The Allves Games did not install the project nor test combat, dialogues, DLCs, or mods in this assessment.

Is there an installer ready to download?

The verified material presents code and scripts for analysis, translation, and compilation. Therefore, this article does not offer a ready-made application button. The documentation requires an Apple Silicon Mac, Ghidra 12, clang, Python, and additional dependencies.

Furthermore, the user needs to provide their own DRM-free copy of the Windows game. The project does not distribute the commercial executable or the RPG data; the generated files must remain on the user's machine.
