The Linux GPU Control Application LACT has been released in version 0.8.1.

[0.8.1] - 2025-08-07

Notable changes:

Full V/F curve editing for older AMD GPUs

The RDNA1, Vega and Polaris GPU generations now expose all of the voltage/frequency points in the UI, and not just the minimum and maximum values like previously.

Note: this it not available on RDNA2/3/4 and likely won't be, as the newer generations are different on the driver level, and use a voltage offset value rather than specific curve points.
Profile hooks

You can now specify custom commands to be executed when a settings profile gets activated or deactivated:

Localization

LACT now supports localization to different languages! There are still a few UI elements that don't allow translations, but there are already several languages that cover most of the UI.
You can also contribute translations using Weblate.

Improved functionality to enable/disable AMD overclocking

The AMD OC enable/disable UI has been updated to be more clear, and to point to enabling OC with a boot flag if automatic setup is not supported on the current system.

Additionally, the builtin option now works on Fedora Atomic systems (including Bazzite).
Lowest/Highest performance levels are now applied correctly when combined with custom clock settings on RDNA GPUs
Detailed GPU cache info reporting on AMD
Fixed extra Nvidia information (such as ROP count) fetching on multi-GPU systems

Packaging info

Starting from this release, -libadwaita variants of packages are no longer provided. See #526 for the reasoning and how to get the libadwaita look using the normal package.

Building from source with libadwaita is still supported to not break third party packages, but it will be removed later.

The full changelog is available on the release page.
