Stuttering in and out of game (AMD 3900X and 2080 TI)

I updated the post with SSD and OS. Thank you for the reminder!

In Windows 10 that's called "Windows 10 Driver Update" which you can google about. W10 can replace your choice of drivers which can lead to odd things like this.

And to be clear this is not "Windows Update."

If you know you are in control then other issues I run into.

1. The PC is driving an UHD 4K display.
A single 2080 is nice but will not always keep up. We need more power like this one: https://www.youtube.com/watch?v=sCfmM71NOTo
2. There's more than W10 installed. Sometimes I find the security suite matters. As none was noted I take it you are stock to the bone.
What could reveal something is sharing a SPECCY web report.
Here's how but I want to preface that you should take this back to the makers and I can't nail this sometimes in a forum and certainly not if it's on a 4K display.

All updates were installed from Nvidia and MSI. Didn't have windows install any drivers besides their windows updates. Windows defender is the only security suite at this point, again pretty stock with minimal programs installed.

I am currently using a Gsync 144 hz 1440p monitor. I had no issues with it with my older pc (GTX 1060, I7 processor on W10), so figured that is not where the issue lies.

I can get a speccy report when I get home from work. Will update with it at that time. Thanks for your help thus far!

You are not in control.

This is new to a lot of folk so here's my workflow on that.
1. Install BIOS version the maker calls out. Turns out to be important on Ryzen systems.
2. Install the W10 OS. Let it update.
3. Install minimal drivers to get it on the web and let it update.
4. Disable Windows Driver Update (again, not to be confused with Windows Update.)
5. Now install motherboard drivers, audio, then graphics drivers and the rest.

REPEAT. Some security suites do cause this complaint. As such at the shop we won't touch this until those are gone. Can be a touchy area for some clients but after being burned (lost days on this) we learned to get the machine clean before we try.)

A SPECCY report may tell more but this is what I can offer without it.

I will try disabling that, doing a fresh install of everything, and see what happens. I will get you the speccy report prior to that to see if you can find any causes of this issue. Thanks!
