Google’s Gemini 4 Argon has been used in an experiment to convert Alan Wake 2 from its x86 Windows version to Arm64 on macOS, with the resulting build reportedly running at more than 140 FPS on an M3 Ultra.
The experiment was shared in an X post by @mweinbach, who described it as his favorite Gemini 4 Argon experiment. He said Argon handled the low-level work required to move the game from Windows and x86 to Apple Silicon and macOS.
Argon Rewrote x86 Operations for Arm
According to @mweinbach, Gemini 4 Argon created Rust bindings for x86 instructions and operations so they could work on Arm.
It also handled the transition from Windows to macOS and converted the game’s graphics shaders to Metal shaders.
The system was built so the converted code could be ahead-of-time compiled, or AoT compiled, without relying on Apple’s Rosetta translation layer.

According to the X post, the converted version of Alan Wake 2 works and reaches more than 140 FPS on an M3 Ultra.
The test shows that Argon was able to handle the translation work needed to run the Windows game natively on Apple Silicon.
The Goal Is to Support More Games
@mweinbach said he is now using Argon to build generalized bindings for more games.
The goal is to determine whether the same approach could work more broadly and allow Windows games to run as native Arm64 macOS software without developers having to create dedicated Mac versions themselves.
He also said he plans to open-source the system once it becomes more reliable and is testing the approach with more major games.
If the method can be generalized successfully, it could provide a new way to bring Windows games to Apple Silicon Macs without relying on Rosetta or requiring a traditional developer-made macOS port.
