Constant 100% CPU usage while gaming

[Zach Trivette]

I recently upgraded my monitor to an acer 1080p 144hz freesync display hoping it would eliminate some stuttering and frame drop problems I was having with my previous monitor, after getting everything set up these problems were gone but I have a whole new problem, I am now experiencing stuttering due to my cpu spiking to 100% usage and dropping in some cases and in other cases it is pinned to 100% constantly, my build is an Intel core i5 9400f with a msi b360m bazooka motherboard, and an msi 1660 ti gaming x with 16 gigabytes of DDR4 at 2666 speed, before I made the monitor upgrade I didn't have this problem with the cpu spikes and high usage so could this be due to my system trying to push the 144hz refresh rate but not being able to maintain it? And could this be alleviated by capping my fps to a more achievable number for my system? Thank you in advance for any help.

Yes and Yes.  

I think if the monitor is the only thing you changed then I would try and cap frames to see if it makes a difference.

If you use v-sync in your games then the fps would be locked to 60fps on your old display

but since you upgraded to 144, your system will try to push out 144frames a second

 

That is the only logical explanation I can think of

Thanks for the responses guys, I tested this out when I got home from work today and that did seem to be the problem, I used Rivatuner to cap my fps to something more reasonable and with G-Sync now everything is buttery smooth with no stuttering or frame drops
