There should be a way change the CPU usage graph so it displays the usage of each individual CPU core in Task Manager.
To see CPU usage per core in Windows Task Manager, open the Performance tab, then right-click on the CPU graph and choose "Change graph to > Logical processors".
If you don't see any of the individual CPU cores reaching near 100% utilization in the task manager graph then you can rule out the spikes being a CPU issue.
I do see the CPU downclocking it's frequency quite a bit. That may be normal and a non-issue so long as none of the individuals CPU cores are going near 100%.
So I did go in to the resource monitor and started checking the individual cores. Even with Windows set for best performance there were still many cores that were parked and you were right some of the cores did reach right at 100%. So I watched some tutorial videos on how to unlock all the cores. After doing that, it has smoothed out the gameplay but there are still CPU spikes (intermittently) on the graph and some micro stutters. However, it isn't doing it nowhere near like it was. I was only able to fit in three or four rounds before I had to stop so I'm still holding my breath to see if it happens again but I imagine this is just a Band-aid or a temporary fix if it continues to work.
