FEX 2601 Brings Various Fixes, Improvements For Wine & DXVK/VKD3D-Proton

Written by Michael Larabel in Free Software on 7 January 2026 at 08:03 PM EST. 18 Comments
FEX, the open-source emulator for running x86 and x86_64 binaries on AArch64 (ARM64) Linux and that is sponsored by Valve and to be used by the Steam Frame, is out with a new monthly feature release.

FEX 2601 updated its thunks for Vulkan 1.4.337 to address some newer Vulkan API extensions not previously supported. This update to FEX will allow newer Mesa/Vulkan drivers to in turn work properly with the latest DXVK and VKD3D-Proton releases making use of those extentions. Ultimately FEX 2601 will ensure more Direct3D Windows titles are now running better on ARM64 Linux.

FEX 2601 also has fixes to some rare hangs within Wine's mutex handling code. Plus there are JIT fixes, a minor Linux system call fix, and more code caching work.
