The Linux GPU Control Application LACT has been released in version 0.10.0.
New additions include Nvidia overclocking options, improved sensor readings, and an interactive setup wizard for the system service.
New Nvidia OC settings: Two new options have been added for Nvidia - PowerMizer mode, which forces the GPU into the highest p-state, and Voltage boost, a slider allowing slightly higher voltages for more overclocking headroom.
More Nvidia sensor readings: The hotspot sensor on Blackwell now works correctly instead of reporting bogus values. Per-memory-chip temperature sensors have been added for GDDR6X/GDDR7 memory, showing both front and back PCB sides on clamshell cards.
Improved initial setup: An interactive wizard now manages enabling the system service, replacing the previous copy-and-paste command dialog.
GTT memory usage display on AMD: A new status bar shows GTT (GPU-accessible system memory) usage, particularly useful on iGPUs to see if the size limit is being hit.
Other improvements:
- Force dark/light theme preference from app settings
- More reliable settings reload on suspend/resume
- Profile hook commands now require polkit authentication
- New
lact cli detach/reattachcommands to temporarily release a GPU from LACT (e.g. to pass it through to a VM)- LACT now ships a polkit policy file, automatically installed with
make install
