[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

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.
