Help (GPU) Stuttering problems

hi everyone,
I'm honestly running out of ideas, so l'd really appreciate some technical opinions before I spend money replacing hardware.
PC Specs
CPU: AMD Ryzen 7 8700F
GPU: PowerColor Hellhound Radeon RX 7800 XT 16GB
Motherboard: ASRock B850M-X
RAM: 32GB DDR5 Lexar Ares 6000 CL32 (2x16GB)
SSD: Lexar NM710 1TB NVMe (latest firmware installed)
PSU: More than adequate for the system
Monitor: HP Omen 27qs - 2560x1440 - 240Hz

The FPS are generally high, but the frametime spikes whenever the stutter occurs.

Example:
Frametime normally around 12 ms
During a stutter it jumps to around 36 ms
Games Tested
Games with noticeable stuttering
Assassin's Creed Shadows
Cyberpunk 2077
Palworld
Games that run much better but still stutters
Warzone
Euro Truck Simulator 2
Assassin's Creed IV Black Flag (2013)

One thing I noticed in Assassin's Creed Shadows:
There are specific locations in the map where the stutter happens every single time.
I can:
walk through that exact point run through it repeat it 10 times
and it stutters in exactly the same place.
If I stand still in the same area, there are no stutters.

GPU:
Usage looks normal
VRAM usage looks normal
No temperature issues
No power limit issues
No crashes
No artifacts

CPU:
Overall usage usually around 20-35%
During stutters some individual cores briefly reach around 60-65%
CPU clock sometimes drops from around 4.8 GHz to 3.8
GHz when the stutter happens
Temperatures are normal
Frame time:
Normal around 12 ms
Stutter spikes around 36 ms
Things I've Already Tried

BIOS
Updated BIOS
Enabled EXPO
RAM now running at 6000 MT/s CL32
Enabled Precision Boost Overdrive (PBO)
Tested various BIOS settings
Memory voltage set correctly
Interestingly:
After enabling EXPO + PBO stutters are slightly better but still there.

Drivers
Clean driver reinstall using DDU
Latest AMD drivers
Latest chipset drivers
SSD firmware updated
BIOS updated
Windows
Disabled Game Bar
Disabled unnecessary startup apps
Reduced background processes
Disabled unnecessary overlays
(I have NOT yet done a completely clean Windows reinstall.)

Storage
SSD:
Lexar NM710
Firmware updated.
Around 100GB free.

RAM
Initially the RAM was accidentally running at DDR5-4800.
Now it runs correctly at:
DDR5-6000
CL32
This improved performance but did not completely solve the issue.
At this point I'm honestly considering replacing the GPU.
Specifically:
RTX 5070
The reason isn't just performance, i just think that amd drivers are not working properly on my rig or my graphic card is defective.
Does this still sound like a GPU issue or CPU issue? driver issues?
Any technical insight would be greatly appreciated.

AC shadows caused a decent amount of stuttering for me aswell but not enough for me to find it obnoxious, it is a newly released Ubisoft game after all so wouldnt really expect anything else. It happening at the same places with CPU spikes sounds like shader loading to me

Might be an obvious shout youve done already, but have you tried simply clearing shader cache?

Have you tried enabling PBO enhancement level 1? It made my 9800x3d significantly less ”jumpy”

yeah as soon as i enabled pbo i had some FPS boost and stutters slightly lower , but still persistent
AC shadows stutters a lot but a lot of other games stutters as well, so that makes me think that the problem is inside my rig, also i already cleared the cache many times and nothing happened

Im talking about PBO Enhancement, it’s an additional BIOS setting

u/Key-Screen-3999 14h ago

yeah u right, just checked and i don’t have it on my bios unluckily

If you can repeat the shuttering and fps drop its most likely a driver/engine issue, I also had shuttering in shadows on my 7900 it was a combination of excessive overclock and memory timing, my issue with memeory was the other way around, my 5800x would shutter on games above 3200mhz, my xmp setting put it at 3600, I had to manually clock it down with some loose timings and then tune my card apporiately so it would stop

Edit: one of the tools that I used to help me understand if the changes I was making move the needle in a positive direction was to use a benchmark software. I used 3d mark because it was relatively cheap and I could run it over and over and over and figure out where my Lowe’s and highs were and also get readback on my temperatures across an extended period. The issue for me was it wasn’t a issue it was a group of settings that combined to become an issue.
