Scope of Linux Support
Path of Exile officially supports Windows, Xbox, and PlayStation. There is an official macOS client available, although - as of June 2025's Patch 3.26 - the application is not yet ARM-native, and thus continues to be dependent upon Apple's Rosetta 2 software.
There has never been an official game client released for Linux - however, Grinding Gear Games has periodically made changes in patches to address issues encountered when playing Path of Exile on Linux through WINE or its derivatives (example).
GGG not officially supporting Linux diminishes the capacity for community-sponsored Linux support efforts.
Below are some questions and answers clarifying the current scope of Linux support on this website.
At present, there are no plans to specifically provide guides for setting up and using the likes of WINE, WINE-based software (e.g. Proton; CrossOver), DXVK, etc. This website has been created by a single person, and existing resources for those tools will do a far better job than could ever be achieved here. It simply doesn't make sense for me to attempt to reinvent the wheel.
An example of a Linux page is the System Information article.
The equivalent main article for this is divided into a dichotomy - Windows users are directed towards creating a DxDiag, and macOS users are asked to generate a System Report. Neither of these are at all suitable for Linux.
Another example of a page in the Linux section is MTR ON LINUX PAGE LINK GOES HERE.
Regardless of if you use GPU-passthrough - when you are using the Windows client in a Windows environment (after a fashion...), you should refer to the main support pages and follow the advice targeting the Windows client.
My goal when communicating is to phrase things in a way that is likely to be understood by the greatest possible proportion of readers. I have a good-faith belief that everyone knows what I refer to when saying "Linux", and that any alternative phrasing would be comparatively less well understood.
