Inno3D TuneIT vs LACT

INNO3D TuneIT OC & RGB Utility V5.02 is a free Windows utility for overclocking and RGB control on listed INNO3D GeForce graphics cards. Its controls include GPU and memory clocks, fan speed, target power, and target temperature. The home page displays GPU clock, temperature, fan speed, memory profiles, driver version, and BIOS version, with real-time GPU monitoring available. RGB settings let users select a mode, change brightness and effect speed, or create a custom effect. Users can also change software startup options. The listed release supports GeForce 50, 40, 30, 20, 16, 10, 900, and 700 Series cards and specifies Windows 11 or Windows 10 64-bit. INNO3D provides a download link and a technical support form requesting product details, hardware configuration, and a problem description. For RMA requests, the support form directs customers to the store where the graphics card was purchased.

LACT is a free, MIT-licensed Linux tool for controlling and monitoring AMD, Nvidia, and Intel GPUs. It reports VBIOS, VRAM, hardware units, Resizable BAR status, and Vulkan features. Monitoring provides configurable historical charts for power, thermals, and frequency, plus throttling information and CSV export. Controls include power caps, AMD power states, GPU and VRAM clocks, and custom fan curves on AMD and Nvidia. Undervolting uses voltage offsets on AMD and VF curves on Nvidia. Profiles can activate according to running processes or gamemode status. A system service applies GPU configuration without depending on a graphical session and can run headless from a configuration file. LACT includes an OpenTelemetry metrics exporter and exposes a JSON API over a Unix socket or TCP. The TCP listener is disabled by default; remote TCP management has no authentication or encryption. Packages are listed for several Linux distributions, with Flatpak and Docker service-only options. Available controls vary by GPU generation, driver, and hardware.
