Active CPU cores spikes

So after I start whatever game, my CPU usage goes up to like 97% and after 10 seconds, it jumps for like 1 second to 30% and back up. I wanted to understand this issue, since it gave massive lag spikes in-game and so I looked in Intel XTU at my cpu temperatures. No thermal throtteling whatsoever, 75C at max.
Then I looked at my active cpu cores and saw that it jumped from steady 4 cores to 1 when the cpu usage dropped. Is there a way to fix this??

CPU: 4720HQ

There is nothing strange with cpu usage spiking. Some applications are single core linked and don't need multicore usage. Stress your cpu with Prime95 and check your cpu usage on all cores to see if it works with full load. The problem may be elsewhere, post your full specs.
