InjectTunnel uses the native Overdrive interface from ATI Catalyst display driver to change core and memory clocks for 3D full-screen or 3D desktop modes. This means the new clocks are applied when a 3D mode is activated. The utility can be used to control a fan speed of the graphics card too. You can even disable fan speed at all! Besides, InjectTunnel measures two independent GPU temperatures by using thermal diodes, reports the current performance state of the GPU, current VRAM and GPU frequencies, GPU voltage, GPU usage, PCI-E clock frequency and PCI-E bus width. InjectTunnel features an intuitive and user-friendly interface that helps to use the utility immediately.
