I have been getting very low 1% and 0.1% FPS numbers that cause stuttering, when otherwise getting a solid 60+ FPS (often having it capped at 60)
It's across multiple games and now also multiple rigs with completely different hardware. In some rigs it has been more frequent/pronounced then others, but has been present in all. My 1% and 0.1% lows drop to 5-25, while I can maintain an FPS at above 60 and even average FPS remains high. I have noticed it tends to coincide with a frametime spike and some kind of CPU ms spike (looking at the Assasins Creed Performance panel thing).

Using MSI afterburner none of the hardware is usually even above 70% usage when this happens. (Monitoring RAM, CPU (all cores), and GPU) Temps essentially never get above 70 c.

It tends to happen more frequently when in urban areas, or when there are multiple "people" in an area/battlefield (be it a strategy game, or RPG etc...) Although this is not always the case as it happens otherwise as well. So far I've noticed it in Assasins Creed Odyssey, Fallout 4 (vanilla not nearly as bad a modded), Total War Warhammer 2, Arma 3, The Witcher 3 and Kingdom Come deliverance. Some are worse than others. Heavily modded Fallout 4 is by far the worst. (All of these games have run through Steam)

I have tried changing so many options and optimizing in so many ways.

Could it be that all of the PSUs were not good quality?

Power Reporting Deviation is quite bad:

Previous PC (same issues):
CPU: i5 9600k
GPU : rx660xt 8GB
RAM: Corsair 16GB 2666Mhz Ram (it's 4000MHZ RAM, but the CPU and MOBO have it clocked at this, hwinfo also says it's running in dual channel 18-18-18-43)
Storage: 500GB nvme samsung evo 970 (OS is on this as well as the games I am trying)
MOBO: MSI B365M PRO-VH (MS-7C31)
PSU: EVGA 600W

Various Benchmark results (only of current rig):

Things I have tried:
-Locking FPS
-Vysnc on/off (as well as third party enforcement of it)
-High Performance mode
-Disable Fast boot
-AMD enhanced performance
-Even trying lowest settings in game(s)
-Fullscreen and borderless windowed mode
-OC RAM
-Different monitors
-Different rooms
-Updating drivers
-freesync
-w controller/without controller
-various BIOS settings
-uninstalling MSI afterburner and RivaTuner
-updated BIOS, GPU drivers, Chipset drivers

Would first update AMD chipset drivers,

AMD Drivers and Support for Radeon, Radeon Pro, FirePro, APU, CPU, Ryzen, desktops, laptops

then update bios to latest version,

https://rog.asus.com/nl/motherboards/rog-strix/rog-strix-b550-f-gaming-model/helpdesk_bios

see if this helps. Might not since you say the Intel system had the same issues, but imo worth it anyway.

Updated both, still same issue. Problem might actually seem a bit worse after having updated.

I have noticed that in Witcher 3 my CPU clock will go from 3775 to 4850 frequently. Even when on high performance mode...

I've benched CPU with various benchmark programs though.

And still problems? Using second and fourth slot from the cpu out? (A2+B2)

Yes, still problems. I noticed I have no issues with red dead redemption 2 though, which is not through steam at all. (Have messed around with steam overlay etc.. though) I noticed the RDR2 seems much more optimized for a multi core CPU, usage is better spread out and tends to not go over 60-70% on any single core. Somewhat drawing a correlation that maybe it's when 70-90% usage on a singe core than it happens...can't quite confirm but seems to me it may have something to do with that.

There was a guy here that had these problems, he used a riser cable, you by any chance too?

Can you show a screenshot of gpu-z?

Not using a riser cable of any kind. GPU is directly into one of the PCie x16 slots.

Here's a shot of GPUz:

I did mention in previous post about potential CPU issue when one core goes above around 75% usage or so. Not really certain, but one of the only things I've noticed that sort of coincides benchmark wise with it. Difficult to tell. As it's not 100% repeatable.

Also, thanks for your time mate
 
6c/6t CPUs seem more vulnerable to wider frame rate variations than 6c/12t and above....; certainly one has no resources to spare, and would need to not think one could stream, fold, do background indexing, cloud sync, AV scan, background video conversion, etc., or anything unnecessary in the background, etc...

Some games might be more vulnerable than others to hitches, especially depending on ones current GPU and frame rate sync/refresh rate; and, I suspect the rigs struggling to maintain to achieve 100 or 144 fps would be more vulnerable as FPS drops below 'x' rates more frequently in certain action gaming scenarios, particularly online with 32+ players, etc...

You look at his old rig,

Yes, currently I'm using the Ryzen 7 5800x. Which is 8 cores 16 threads.
I have a friend who has the same CPU and no issues.

Interestingly Fallout 4 Vanilla runs quite smooth. Tried multiple modlists and it just tanks performance, getting those big FPS drops. Biggest correlation I can make is CPU utilization on single core(s) that goes above 70% or so. My friend runs same modlists with no issue with same CPU and equavilant GPU (2060 super).
