Check your power plan in settings in windows (Control Panel\All Control Panel Items\Power Options), usually for laptops they are on balanced, you have to put it on high performance (assuming you keep the laptop plugged in).
Also, if you use the cpu for mining at the same time, expect some throttling.
Thank you for your reply,
Settings are already on High Performance (That was the first thing I changed before I even started the mining)
I'm not using the CPU for mining.
Today, I tried MinerGate v7.2 (Windows) and tried GPU mining Bytecoin, and I get the same GPU usage (Using 4 cores - The max it offers)
GPU stays steady at 16%
I'm trying to find online resources, but only find people who would like to lower their GPU usage from 100% down to a lower value.
But even with my difficulty set to the max, I still can't get past 16%
