Low CPU/GPU Usage, Bad Performance

[Helios]

That laptop is more than enough for Dolphin.

You probably have v-sync forced somewhere in the rendering stack and that's causing Dolphin to lock a 60 fps to 30 because maybe you're dropping a frame or something.

Check your driver and Dolphin settings.

Also, are you plugged in? I know a lot of modern laptops will throttle GPUs to lower framerates to increase battery life.
