[SOLVED] Microstuttering and CPU usage spikes while gaming

[ThaDevilsJester]

CPU: Intel i9-9900k
GPU: Nvidia Geforce 1080
Motherboard: Gigabyte Z390 AORUS LGA1151
Hard Drives: 1xWD SSD 500GB, 2:WD HDD 1TB
RAM: 16GB DDR4

I'm having issues and I'm hoping someone more knowledgeable than me can help. As mentioned above, I have a pretty darn good PC built. However, when playing games (I play a lot of them but this happens mostly with Rainbow Six Siege, Cuisine Royale, and occasionally Call of Duty MW 2019), I'll get random and intermittent CPU spikes, causing the game to just stall for a second or two and usually get me killed. It does this more in firefights but can just randomly happen while walking around doing nothing. I've watched task manager and have narrowed it down to the CPU (it's the only part that goes from 70-80% usage, up to 100% for a second or two, then back down to 70%-80% like nothing happened) but I can't figure out what's causing it. I play around with VR and it doesn't have this issue, but a game like Cuisine Royale can freeze the game for a few seconds at a time. Why is doing this when I have one of the leading processors available? Can someone please help? Also, if it helps, the only driver updates I've done have been Windows 10's driver updates and the Geforce driver updates.

Rainbow Six Siege is on the Ssd, Cuisine and CoD are on separate HDDs

Having the same problem, input feels laggy also, I heard it could happen cause you didn't newly install Windows after new motherboard, did you just use the SSD with Windows from your old PC or did you install fresh? I didn't install fresh after swapping a motherboard so I want to know.

I didn't fresh install on my SSD either but, if memory serves, it may have done it occasionally before I upgraded. I had the i7-7700k before and it would do the same thing sometimes if I remember correctly. It's just doing it more now.

Can you do it and update me if it helped? I have too much stuff to backup for a fresh install, thanks

Run HWmonitor.
Look for a max cpu temperature of 100c.
That would indicate that you throttled and reduced performance momentarily until temperatures were back under control.

What is the make/model of your case and cpu cooler.
Try taking the case covers off and direct a house fan at the innards. If that helps, look to case cooling fixes.
