This is the best summary I could come up with:

The open-source FEX-Emu project continues advancing as an emulator to run x86/x86_64 Linux binaries on 64-bit ARM (AArch64), even for games, Valve’s Steam Play / Proton, and other complex software.

FEX-Emu 2308 is out today with more performance optimizations and other features implemented for this emulator.

FEX-Emu 2308 has been working on more performance optimizations to handle x86/x86_64 emulation faster with items like faster unaligned memory accesses, optimized x87 memory accesses, optimizing vector TSO load stores, and optimizing other x86 instructions.

There’s also been bug fixes, MinGW build improvements, and implementing other missing features.

FEX has already proven itself capable of running x86/x86_64 games on AArch64, including with Steam Play (Proton).

I’m a bot and I’m open source!

We’re not ready to move to ARM yet, but it’s looking like there will come a day where we need to be ready, and projects like this will help.

Looks interesting. I tried only Box64/86. Wondering how this will compare.
