[0.5.4] - 2024-04-22

Major new features:

• Historical charts

  Added a dedicated window that shows clockspeed, temperature and power usage values over a period of time. Thanks to @In-line for the initial implementation.

• Fan control hysteresis

  There are two new settings for custom fan curves: spindown delay and speed change threshold. These settings help avoid unwanted fan speed changes caused by small temperature changes and short temperature drops (such as during a loading screen in a game for example), reducing fan noise.

• VBIOS dumping

  It is now possible to dump the current GPU VBIOS into a file (the option is in the dropdown menu).

• Automatic config reloading

  Now when you manually edit the config file in /etc/lact/config.yaml, LACT will automatically apply the changes. This can be useful in headless environments.

There are also some hardware handling fixes and usability improvements, see the full changelog below.

If you want to support the development of LACT, please consider sponsoring.
