# FEX: Emulate x86 Programs on ARM64
|
|
FEX allows you to run x86 applications on ARM64 Linux devices, similar to qemu-user and box64.
|
|
It offers broad compatibility with both 32-bit and 64-bit binaries, and it can be used alongside Wine/Proton to play Windows games.
|
|
|
|
It supports forwarding API calls to host system libraries like OpenGL or Vulkan to reduce emulation overhead.
|
|
An experimental code cache helps minimize in-game stuttering as much as possible.
|
|
Furthermore, a per-app configuration system allows tweaking performance per game, e.g. by skipping costly memory model emulation.
|
|
We also provide a user-friendly FEXConfig GUI to explore and change these settings.
|
|
|
|
## Prerequisites
|
|
FEX requires ARMv8.0-a or newer hardware, with minimum extensions FEAT_FP and FEAT_CRC32.
|
|
|
|
It has been tested with the following Linux distributions, though others are likely to work as well:
|
|
|
|
- Arch Linux
|
|
- Fedora Linux
|
|
- openSUSE
|
|
- Ubuntu 22.04/24.04/24.10/25.04
|
|
|
|
An x86-64 RootFS is required and can be downloaded using our `FEXRootFSFetcher` tool for many distributions.
|
|
For other distributions you will need to generate your own RootFS (our [wiki page](https://wiki.fex-emu.com/index.php/Development:Setting_up_RootFS) might help).
|
|
|
|
## Quick Start
|
|
### For Ubuntu 22.04, 24.04, 24.10 and 25.04
|
|
Execute the following command in the terminal to install FEX through a PPA.
|
|
|
|
```sh
|
|
curl --silent https://raw.githubusercontent.com/FEX-Emu/FEX/main/Scripts/InstallFEX.py | python3
|
|
```
|
|
|
|
This command will walk you through installing FEX through a PPA, and downloading a RootFS for use with FEX.
|
|
|
|
### For other Distributions
|
|
Follow the guide on the official FEX-Emu Wiki [here](https://wiki.fex-emu.com/index.php/Development:Setting_up_FEX).
