WoW64 is finally complete

Even 16-bit applications work

If NTSYNC is the headline feature, the completion of Wine's WoW64 architecture is the change that will quietly improve everyone's life going forward. On Windows, WoW64 (Windows 32-bit on Windows 64-bit) is the subsystem that lets 32-bit applications run on 64-bit systems. Wine has been working toward its own implementation of this for years, and Wine 11 marks the point where it's officially done.

What this means in practice is that you no longer need 32-bit system libraries installed on your 64-bit Linux system to run 32-bit Windows applications. Wine handles the translation internally, using a single unified binary that automatically detects whether it's dealing with a 32-bit or 64-bit executable. The old days of installing multilib packages, configuring ia32-libs, or fighting with 32-bit dependencies on your 64-bit distro thankfully over.

This might sound like a small quality-of-life improvement, but it's a massive piece of engineering work. The WoW64 mode now handles OpenGL memory mappings, SCSI pass-through, and even 16-bit application support. Yes, 16-bit! If you've got ancient Windows software from the '90s that you need to run for whatever reason, Wine 11 has you covered.

For gaming specifically, this matters because a surprising number of games, especially older ones, are 32-bit executables. Previously, getting these to work often meant wrestling with your distro's multilib setup, which varied in quality and ease depending on whether you were on Ubuntu, Arch, Fedora, or something else entirely. Now, Wine just handles it for you.

The rest of Wine 11 isn't just filler

There are more fixes, too

It's easy to let NTSYNC and WoW64 steal the spotlight, but Wine 11 is packed to the gills with other stuff worth talking about.

The Wayland driver has come a long way. Clipboard support now works bidirectionally between Wine and native Wayland applications, which is one of those things you don't think about until it doesn't work and it drives you mad. Drag-and-drop from Wayland apps into Wine windows is supported. Display mode changes are now emulated through compositor scaling, which means older games that try to switch to lower resolutions like 640x480 actually behave properly instead of leaving you with a broken desktop. If you've been holding off on switching from X11 to Wayland because of Wine compatibility concerns, Wine 11 removes a lot of those barriers.

On the graphics front, EGL is now the default backend for OpenGL rendering on X11, replacing the older GLX path. Vulkan support has been bumped to API version 1.4, and there's initial support for hardware-accelerated H.264 decoding through Direct3D 11 video APIs using Vulkan Video. That last one is particularly interesting for games and applications that use video playback for things like cutscenes or in-game streaming.

Force feedback support has been improved for racing wheels and flight sticks, which is great news if you're running a sim setup on Linux. As well, Bluetooth has received a new driver with BLE services and proper pairing support, MIDI soundfont handling has been improved for legacy game music, and there are a couple of minor extras like Zip64 compression support, Unicode 17.0.0 support, TWAIN 2.0 scanning for 64-bit apps, and IPv6 ping functionality.

Thread priority management has been improved on both Linux and macOS, which helps with multi-threaded application performance beyond just the NTSYNC gains. ARM64 devices can now simulate 4K page sizes on systems with larger native pages, which keeps the door open for Wine on Arm hardware. And with more Arm-based Linux devices showing up every year, that matters more than it used to.

Plus, there are a ton of bug fixes. Games like Nioh 2, StarCraft 2, The Witcher 2, Call of Duty: Black Ops II, Final Fantasy XI, and Battle.net all received specific compatibility fixes, which is additional to the broader improvements made across the board that will improve performance and compatibility across significantly more titles.

Wine 11 is a big release, and it's not just NTSYNC that makes it the case. Sure, NTSYNC alone would have made it worth paying attention to, but combined with the WoW64 completion, the Wayland improvements, and the sheer volume of fixes, it's the most important Wine release since Proton made Linux gaming viable. Everything built on top of Wine, from Proton to Lutris to Bottles, gets better because of it. If you play games on Linux at all, Wine 11 is worth your time trying out.
