- Proton (SLR and Native)
- Update release of the previous one, based on
10.0-20260312 - Bundled DXVK-NVAPI's Vulkan Reflex layer to support Reflex in Vulkan games. Enable using
PROTON_VKREFLEX=1 - Allowed Wayland server-side decorations to work out-of-the-box. In case there is an issue due to decorations,
PROTON_NO_WM_DECORATION=1(or the originalWAYLANDDRV_SSD=0) will disable them. - Updated DXVK and vkd3d-proton to latest
- Imported fixes for Crimson Desert / Death Stranding 2 from upstream Proton Experimental Bleeding Edge
- Disabled

- Update release of the previous one, based on
- Proton (SLR specific)
- None
- Proton (Native specific)
- The native
proton-cachyosversion (the one not using the Steam Linux Runtime) is most likely going to go away soon. With the new SteamRT3 Steam beta we will likely need to rethink how to achieve the way of launching outside of any runtime container, as Steam itself will be in a container. Also I do not think it's that much useful any more, and more of a chore to keep it going than anything. It remains to be seen, but consider this is a very early heads-up.

Note
We have been building arm64 packages of Proton-CachyOS for the past few versions. They are now part of the release but they are untested and possibly
broken. To use this build you will need to get and build a development version of umu-launcher from https://github.com/Open-Wine-Components/umu-launcher.
From the CLI interface it should work normally by pointing PROTONPATH to this proton build. If you want to enter the steamrt4 container to inspect it
without running proton, you can do so by running PROTONPATH=umu-steamrt4-arm64 umu-run xterm.
I also provide unpatched builds of Proton Experimental with support for umu-launcher in my personal repository
https://github.com/loathingKernel/Proton/releases which can be used for testing arm64
We are looking for testers, if you are interested, feel free to contact me (@loathingKernel) in the CachyOS Discord server.
Important
I know that we have a lot of different packages that might cause confusion. My suggestion is to be conservative and use x86_64. The x86_64_v2
and x86_64_v3 should be absolutely identical between them and with x86_64 across the board, and x86_64_v4 can be worse in some cases.
Feel free to experiment and see which fits better for your system, of course.
Warning
This release includes a x86_64_v4 package. This package is largely untested and experimental.
It may exhibit issues or completely refuse to work. Use at your own discretion and report issues here only.
