Installation
- Download
Decky.LSFG-VK.Experimental-0.13.0-experimental.7.zipbelow. - On the Steam OS, open Decky Loader's settings and enable Developer Mode.
- Choose Developer → Install Plugin from Zip, then select the downloaded ZIP.
- In the plugin, select Install Experimental LSFG-VK (developer build) and add
~/.local/bin/lsfg-vk-experimental %command%to the game’s Steam launch options.
Updating an existing experimental installation
- Quit games currently launched with
~/.local/bin/lsfg-vk-experimental. - In Game Mode, choose Developer → Install Plugin from Zip and select this newer ZIP. Do not uninstall the experimental plugin first.
- Reload the plugin from Decky, or restart Game Mode if it does not reload automatically.
Existing experimental profiles, private layer files, and Steam launch options are retained. The public/original plugin may remain installed, but use exactly one plugin wrapper per game.
Important
- This is an experimental build; test it per game.
- The public and experimental plugins can coexist; select exactly one LSFG-VK wrapper per native Steam/Proton game.
- The isolated experimental wrapper bypasses other global implicit Vulkan layers (such as vkBasalt) for that game.
- Confirm the detected
Lossless.dllpath before launching. Leaving it blank permits lsfg-vk automatic discovery.
