[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/reattachcommands 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.
