CodeWeavers launch a new CrossOver Preview adding Linux ARM64 support

Gaming on Linux with ARM64 is about to get more interesting, with the team at CodeWeavers announcing a new CrossOver Preview. They said this has been years in the making through different releases of Wine gradually adding more of what's been needed.

What is CrossOver? It's from the team that support Wine development, which adds their own UI and tooling on top of Wine to make the experience a little bit easier, along with dedicated support. Some of their team also work with Valve on Proton.

From the blog post:

In January 2024, ARM64 support was released in Wine 9.0 for running native Windows ARM binaries and emulated i386 code. In May 2024, the CrossOver team completed work making a native ARM64 CrossOver client. The Wine 10.0 release in January 2025 included full support for ARM64EC to run emulated x86-64 code. Tackling ARM64EC involved not only significant Wine development, but also extensive compiler development to essentially implement a brand new architecture. The existing LLVM toolchain already had support for ARM64, and Wine developers worked on the ARM64EC support that was included in the LLVM 21 release. Finally, once ARM64EC development was complete in upstream Wine, the CrossOver team integrated FEX into CrossOver to handle i386 and x86-64 emulation and our QA team completed an extensive testing sweep.

CodeWeavers have been testing on the System76 Thelio Astra which has an Ampere Altra CPU and an NVIDIA RTX 4060 Ti with Ubuntu 24.04. In their testing they were able to see these results:

Game	Average FPS
Cyberpunk 2077	120
Hades II	60
Path of Exile 2	60
Ghost of Tsushima	50

That's a pretty expensive system though.

Really interesting tech, and continues to show what's possible with open source. CodeWeavers' Meredith Johnson notes how "we envisage CrossOver as a viable solution for migrating enterprise Windows workloads to Linux for improved security and reduced bloat".
