ASUS GPU Tweak III vs Inno3D TuneIT

ASUS GPU Tweak III is free Windows software for adjusting parameters on NVIDIA and AMD desktop graphics cards, including overclocking, voltage, and fan control. OC Scanner automatically optimizes clock speeds for NVIDIA cards and saves a profile without overwriting driver data. The Voltage-Frequency Tuner manages the GPU boost curve through multiple input methods. Profile Connect can load linked overclock, fan-curve, and OSD settings when a selected application runs. Users can configure GPU fans and system fans connected to FanConnect headers with curves or fixed RPM settings. Monitoring includes fan RPM and system power metrics, system information over full-screen apps, and log export for analysis. A hardware plug-in adds real-time component statistics, while the OSD has adjustable display properties. ASUS lists Windows 10 and 11, 2 GB RAM, and 200 MB storage as minimum requirements for most versions. Power Detector+ compatibility is limited to specified ROG cards. The listed stable release is version 2.1.9.5, dated September 18, 2026.
