Das Linux GPU Control Application LACT wurde in der Version 0.7.2 veröffentlicht.

[0.7.2] - 2025-03-16

Main changes:

RDNA4 support! LACT now works on RX 9070 series GPUs with functional clocks settings, power limit and fan control.

Special thanks to @Lawstorant who submitted several kernel patches that improve driver-side behaviour as well as helped with testing this.
For RDNA4, you need recent versions of the kernel (at least 6.13, 6.14 preferred) and linux-firmware at least from late february.

Note: the current version of the driver's overclocking interface has some issues that @Lawstorant has submitted patches to fix.
LACT is currently able to handle interfaces both from the current kernel versions with some workarounds, as well as the fixed ones from patches that will likely land in kernel 6.15+.
Once these patches are widely available, LACT will stop supporting workarounds for kernel 6.13/6.14 in a future version.

Nvidia locked clocks support

It is now possible to set a min and max GPU and VRAM clock using nvidia's locked clocks feature.
When combined with the offset setting, it's possible to indirectly undervolt Nvidia GPUs.
See #486 for more info.

More detailed Nvidia information

LACT is now able to query the Nvidia driver directly to read information that is not exposed through NVML.
This allows it to read some new hardware info fields: ROP count, SM count, VRAM type and vendor.

Historical charts now follow the GTK theme as much as possible, instead of always having black lines over a white background

More reliable fan control handling after GPU reinitialization operations such as suspend/resume
