I've noticed that Asus GPU Tweak, last release, waste my cpu also in idle, also when the program is on the systray...
The process 3D_enable_G consume till 15% of my cpu.
Is there any reason for it?
Is it normal?
Monitor of FAN, temperature, ecc is disabled.

After I close the application, the process 3D_enable_ecc still on memory.

My specs: Intel I7-3770k@4.4GHz, Asus R9280X-DC2T-3GD5, Windows 8.1 x64, AsRock Z77 Extreme 6 Motherboard, 16GB RAM.
