So I've tried to look into the power options to change this problem. I've set the "while on battery" Processor maximum and minimum state to 100%. I just want to be able to unplug and not have my frame rates and performance drop.
Most laptops have features that throttle down both the GPU and the CPU when you run on battery in order to save power. For the CPU, the feature is called speedstep for Intel CPUs. You have to go into the BIOS to disable this feature. For your GPU since it's a NVidia card, you'd most likely have to go into the NV control panel and either look for power settings or a section called PowerMizer.
Note: your battery life will drop like a rock since both the CPU and GPU will run full tilt.
It might be listed under EIST or C1E. Try and find the power feature for your GPU since that is more important while gaming anyway. The CPU will, in most cases, override SpeedStep when you put it under load on battery or not.
Ok... if you go into power management in Windows, see what happens if you change the power plan to high performance. The only other thing I can think of is Asus just has your laptop locked down pretty tight.
