FEX 2507 Brings New Optimizations & Gets Some Ubisoft Games Running

Written by Michael Larabel in Linux Gaming on 8 July 2025 at 05:57 AM EDT. 5 Comments
FEX 2507 is now available for this open-source emulator that allows running x86/x86_64 games and applications atop 64-bit ARM Linux devices whether they be AArch64 servers or ARM64 single board computers and other devices.

A notable milestone with today's FEX 2507 release is implementing enough support for running the Ubisoft Connect launcher and in turn being able to run some Ubisoft game titles. The Ubisoft Connect launcher had been "a thorn in our side for years" according to developers due to its built-in anti-debugger tech. That has prevented all Ubisoft games from launching but now with FEX 2507, enough support is in place that some Ubisoft games can be played.

FEX 2507 also brings optimized x87 FISINCOS handling, optimized long division, and other optimizations. There is also a physics fix helping the game Horizon Zero Down.
