I see many complaints about gaming laptops not performing well.
Usually gaming while plugged in.
One common cause is thermal throttling.
Laptop coolers must, of necessity be small and light.
The coolers are also relatively underpowered.
If you run an app such as HWMonitor or HWinfo, you will get the current, minimum, and maximum cpu temperatures.
For intel processors, if you see a max of 100c. it means you have throttled.
The cpu will lower it's multiplier and power draw to protect itself
until the situation reverses.
At a lower multiplier, your cpu usage may well be at 100%
What can you do?
First, see that your cooler airways are clear and that the cooler fan is spinning.
It is counter-intuitive, but, try changing the windows balanced power profile/ advanced functions to a max of 99% instead of the default of 100%
That may keep an aggressive bios from driving the cpu too hard.
You may not notice the reduced cpu performance.
On getting added airflow through the cooler, I would prioritize getting cooling air INTO the cooler.
It will eventually exit somewhere, hopefully taking component heat with it.
