• feat: show additional clock domains in UI

• fix: tests

v0.10.0

[0.10.0] - 2026-08-12

Highlights:

• New Nvidia OC settings

  Two new options added have been added for Nvidia:

  • PowerMizer mode

    This setting lets you force the GPU into the highest p-state. This is similar to the "performance level" setting on AMD.

  • Voltage boost

    This slider can be used to allow the GPU to boost to slightly higher voltages. This is not a full voltage offset setting, and only allows for slightly more headroom, but it might be beneficial for some OC setups.
    If you've used MSI Afterburner on Windows, this setting is the voltage slider in the main window.

• More Nvidia sensor readings

  The hotspot sensor on Blackwell now works with a Blackwell-specific path, instead of reporting bogus values.

  Support for per-memory-chip temperature sensors has been added. This works on GPUs with GDDR6x and GDDR7 memory, including showing both front and back sides of the PCB for clamshell cards.

  Thanks to Paulo Games, who initially found these sensors and shared his discoveries with the project.

• Improved initial setup

  When installing LACT, you have to enable the system service in order to use a lot of the functionality.

  Previously, you would get a dialog telling you to copy and run a command to enable the service.

  Now, there is an interactive wizard to manage the service. This should make the setup process easier for new users:
  

• GTT memory usage display on AMD

  There is now a status bar for GTT (GPU accessible system memory) usage. This is particularly useful on iGPUs to see if you are hitting the size limit when running VRAM-heavy applications.

  

• Other improvements:

  • You can now force dark/light theme preference from app settings
  • Reloading settings on suspend/resume is now more reliable
  • Setting profile hook commands now requires admin auth through polkit
  • lact cli detach/reattach commands have been added to allow to "release" a GPU from LACT. The target use case is to temporarily ignore a GPU in order to allow it to be attached to a VM.

Packaging info

LACT now ships a polkit policy file. It is automatically installed with make install.

v0.9.1

[0.9.1] - 2026-06-25

Highlights:

• Display information

  LACT will now show information about the connected displays.
  Currently it is quite basic, but it does show the active connection information for DisplayPort:

  

• Nvidia VF curve editor improvements

  The curve editor now works on Turing (RTX 2000/GTX 1600 series) GPUs.

  It is also now possible to select a section of the VF curve, and move all the points in it together:

  

• Improve handling of the power cap on AMD

  Previous versions of LACT would crash on RDNA3 (RX 7000 series) cards when running 7.0.13/7.1 kernels due to an AMD driver regression where the power limit is reported as 0.
  The driver bug should be fixed shortly, but these improvements will keep LACT functioning meanwhile.

  Additionally, the same driver changes for RDNA3 also affected the allowed power limits, leading to a lowered maximum limit on some cards.
  This is now handled more gracefully on LACT's side, so that existing configs that might have an older, higher power cap will still be applied properly.

• Faster UI startup

  LACT now starts much faster by fetching Vulkan/OpenCL info in the background, rather than waiting for it at startup.
  There is also a cool loading animation on the software page while this info is not ready.

• QOL UI improvements

  • Process search in the profile editor will no longer show garbage empty-name processes, and the search is case-insensitive
  • Window size is now remembered across restarts
  • App references and exit now have keyboard shortcuts
  • The historical graphs edit options are now behind a sliding banner
  • Information/Error dialogs across the app are now more consistent

• Nvidia target temperature setting is no longer mutually exclusive with a custom fan curve

• AMD deep sleep p-state is now properly shown in the p-states list

• Reloading devices (such as on suspend/resume) no longer leaks AMD DRI file descriptors

Support

Packaging info

libdisplay-info is a new system dependency.
It is required by default, but it is possible to build LACT without it by disabling the display-info cargo feature.

v0.9.0

[0.9.0] - 2026-04-25

This is a pretty big release, with major UI changes and a long-awaited feature for Nvidia users.
Primary changes:

• UI Update (#951, #972, #975 and others)

  The UI has been reworked with a new layout and lots of styling changes. Overall, it should be much nicer to look at and use, without sacrificing information density.

  

  An important technical change is that LACT now utilizes libadwaita, rather than plain GTK4. The focus in GTK development over recent years has been almost entirely on libadwaita, and this decision allows LACT to make use of various new widgets, layouts and other improvements from the ecosystem.

  For the KDE users who are worried about the application looking out of place with the rest of the system, there is an in-app Breeze theme option that will be enabled automatically if Breeze is your system theme. It should in fact look better than before, as the global breeze-gtk theme often did not work well with GTK4 and caused elements to be missized or have missing icons.

• Nvidia Voltage-Frequency Curve Editor (#957)

  While previously considered not to be available on Linux, LACT now has a VF curve editor for Nvidia GPUs that allows for more precise tweaking in a similar manner to Windows tools such as MSI Afterburner.

  An very important note is that this editor relies on entirely undocumented driver functionality, and as such there are zero guarantees regarding its stability or safety. There haven't been any issues discovered during testing and the behaviour has been cross-compared with known Windows tools. But nothing stops Nvidia from removing it in a future driver version for example.

  I also want to express my thanks to @Ristovski, who has helped with the reverse engineering efforts to get this feature working.

  

• Nvidia target temperature setting (#917)

  Also known as acoustic target, this option allows you to set the target temperature that the card will try to maintain, without needing to use an entirely custom fan curve.

• AMD Hardware blocks information reporting (#942)

  You can now see which hardware IP blocks your AMD GPU has.
  For example, this can be useful to check which hardware encoder (VCN) generation you have.

• More AMD hardware quirks

  • Voltage settings are now applied properly on some specific Vega cards (#974)
  • Custom clock settings now work on Phoenix iGPUs (#948)

• Better Flatpak service reliability (#902 and a few others)

  This makes the host service that's installed by the Flatpak version work more reliably across different setups.
  One notable case is that this resolves permissions errors with Nvidia GPUs on systems with AppArmor (most Ubuntu-based distributions)

Packaging info

Notable dependencies on this version:

• Rust 1.93+
• libadwaita 1.5+
• GTK 4.14+

Due to the increase in the minimum GTK version requirement, packages for Ubuntu 22.04 and Debian 12 have been dropped.

v0.8.4

[0.8.4] - 2026-01-25

This release primarly contains various UI refinements and bugfixes.
Primary changes:

• UI Improvements

  There have been various interface improvements in this release (mostly contributed by @makarov-roman).
  The OC page received the most changes:

  

  There are also various QOL changes, such preserving the selected tab between app restarts, dragging the fan curve is now more responsive, and the process monitor handles long process names correctly.
  Additionally, the historical graphs window no longer looks blurry when using fractional scaling. It also now uses fewer system resources for rendering.
  Overall the UI is now more consistent and should be nicer to use.

• Docker packaging

  LACT is now available as a Docker image. This image only includes the daemon/CLI without the UI, is primarily intended for headless servers.
  An example use case is using LACT as a metrics exporter on a server with an Intel ARC card for transcoding.

• Additional power sensors are now available on AMD

  For example, you can now have a graph for CPU/GPU power usage split on mobile APUs.

• Notable bugfixes/improvements:

  • The daemon no longer needlessly keeps AMD GPUs with ROCM OpenCL awake
  • Various dialog windows no longer leak memory when repeatedly closing/opening them
  • Reconnecting to gamemoded no longer leaves zombie dbus listener processes
  • The skin temperature sensor no longer shows thousands of degrees on certain mobile AMD platforms
  • Stats fetching on AMD is now more efficient
  • Panics in the GUI will now show an in-application bug screen, instead of hanging the application
  • Vulkan schema has been updated to 1.4.340 (this includes showing if the widely anticipated VK_EXT_descriptor_heap extension is supported)

v0.8.2

[0.8.2] - 2025-10-18

Main changes:

• OpenTelemetry metrics exporter

  The daemon now supports exporting GPU metrics to an OpenTelemetry-compatible server.
  This is primarly useful for server setups, when you want to have a history of GPU usage over time.

  See the docs for how to enable it.

  

• CLI additions

  The previously very basic CLI now has more functionality. New commands:

  • lact profile for managing settings profiles, such as setting the current profile or toggling automatic switching
  • lact power-limit for power cap configuration
  • lact stats for GPU monitoring

• UX Improvements

  • On a multi-GPU system, the UI will now default to selecting the first detected dGPU (previously the iGPU was often the default option)
  • Historical charts now show the average stat value (hidden behind the info button)
  • Historical charts are now more responsive to input (such as resizing the window or editing stats)
  • It is now possible to change the stats polling rate in the UI for reduced resource usage
  • Dynamic numbers in the UI now use mono fonts to avoid the text sliding around (it was noticeable with the new default Gnome font)

• Flatpak improvements

  • The UI will now use a dark theme based on system preference (See #585 for more info - the lack of full theming support is a flatpak limitation in GTK4 apps)
  • Automatic profile switching based on gamemode being active now works in flatpak
  • Flatpak build bundles are now included in GitHub releases

• Various translation updates

  Thanks to community contributions on Weblate, LACT is now fully localized in German, French, Czech, Portuguese, Chinese and Arabic (barring RTL language issues), as well as several other languages that are partially translated.

• Intel Battlemage power limit setting fix

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.
  Example from a Vega 56:

  

  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.

v0.8.0

[0.8.0] - 2025-06-28

Main changes:

• More advanced profile management

  You can now set multiple conditions to trigger profile activation, such as having any or all processes in a list running:
  

  It is now also possible to export and import profiles to json files.

• Process monitor

  There is a new process monitor window (available from the dropdown menu on the top right) showing the list of processes that are using the GPU, with engine load and VRAM usage stats:
  

  The monitor is supported on all 3 GPU vendors (using /proc fdinfo on AMD/Intel and NVML on Nvidia)

• More Nvidia metrics

  The following new readings are now available on Nvidia: GPU voltage, GPU hotspot temperature, VRAM temperature (GDDR6 only):
  

  Big thanks to @Ristovski who helped with figuring out on how to fetch this information.

• Power profiles daemon integration

  Previously when running LACT together with power-profiles-daemon, ppd would override some settings as it has its own amdgpu management features. Now LACT detects if power-profiles-daemon is present on the system, and will automatically disable the conflicting functionality through ppd's dbus API (without affecting anything else that ppd manages).

  Note: this needs power-profiles-daemon 0.30 or later to work.

• Flatpak service improvements

  The service in the Flatpak version of LACT has been updated to use flatbox. This makes it work more consistently across different system setups as it avoids the need for the system service to directly call flatpak as another user to run the service.

  Note: after updating, you will be prompted to re-setup the service. This is normal, and is needed to update the systemd unit to the new format.

  Warning as of 2025-06-30, the updated Flatpak package currently has some issues with AppArmor on Ubuntu-based distributions: #647

Important notes:

• RDNA4 GPUs now require kernel 6.14 or later for overclocking to work. Older kernels had broken clockspeed control behaviour that LACT contained a workaround for, and this workaround has now been dropped. See #599 for more info.
• There is a new workaround for RDNA3 constantly reporting thermal throttling, it should now be reported only when it's actually affecting performance.
• If multiple Vulkan drivers are available (such as both RADV and AMDVLK), LACT will now let you select between them on the software page.

v0.7.4

[0.7.4] - 2025-05-11

This is mainly a refinement release, but there are some new features as well. Key highlights:

• New fan control UI

  The custom fan curve UI is now an actual curve that you can drag around, instead of being a series of sliders.

  

  There is now also an option in the UI to set which temperature sensor is used for the curve (this only works on 6000 series and older AMD cards due to hardware limitations).

• Automatic fan mode threshold on Nvidia

  Most Nvidia GPUs support turning the fan off below a certain temperature, but this only works in the automatic fan control mode. When using manual controls such as a custom fan curve in LACT, the GPU limits possible fan speeds between 30% and 100%.
  It is now possible to work around this by switching the fan control to automatic below a configured temperature, allowing the fan to turn off at lower temperatures even when using a custom curve.

• More information reporting

  There is some new information that is now reported by LACT:

  • OpenCL details, including supported versions and basic hardware properties
  • GPU instruction set version on AMD
  • ROP count on AMD

  

• New config API

  There is a new API for GPU configuration in the unix socket that reuses the same format as the config file.
  Thanks to this new API, the GUI will now ask confirmation for all settings (and automatically revert if not confirmed), while previously this only worked for clockspeed/voltage settings.

• Finished GUI refactor

  All UI components now use the Relm4 library to define GTK UIs. This also resolves some problems with the UI starting to lag after applying settings serveral times related to GTK signals handling in the old implementation.

Additional notes

• LACT is available on Flathub!

  Note: the Flatpak version of LACT installs a system service outside of the sandbox. This might not work on unconventional setups such as NixOS or systems with an encrypted home directory. In such cases you should to stick to native packages for the time being.

• This version still provides libadwaita-flavoured packages, but they will be dropped in the future. The only difference between the normal and libadwaita editions is the default theme. See #526 for further justification and how you can get the libadwaita look using the normal version.

• If you find LACT useful, please consider sponsoring on liberapay or ko-fi
