What is LACT?
This application allows you to control your AMD GPU on a 
Linux kernel system.
Current features:
Detailed GPU information reporting
- Name and manufacturer
- VBIOS info
- VRAM info (Type/Manufacturer/Bus)
- Hardware unit info (CUs/SMs/EUs, ROP count)
- Resizable BAR status Vulkan features and extensions Monitoring
- Configurable historical charts for power/thermals/frequency
- Throttling info
- Data CSV export Power configuration
- Power cap
- Power states (AMD only)
- Thermals configuration
- Custom fan curves (AMD/Nvidia)
- GPU firmware thermal options such as thermal and acoustic target/limit (AMD RDNA3+ only) Overclocking
- GPU/VRAM clocks configuration
- GPU undervolting (via voltage offset on AMD, VF curve on Nvidia) Settings profiles
- Automatic profile activation based on running processes or gamemode status OpenTelemetry metrics exporter
GPU configuration is handled by a system service that does not depend on a graphical session (Wayland/X11).
The service can also be used standalone with a config file, for example in headless scenarios.

easier than afterburner to undervolt. and works a fucking charm
Was very easy to install and configure, works as expected, 20% performance boost simply by increasing the power limit to the max supported value, same as in MSI Afterburner.
