Frametime spikes and stuttering after switching to AMD CPU?

check out PowerSettingsExplorer - theres alot of HDD settings, and PCIE link settings that can cause issues - see if messing with it helps.

Particularly the "NVME Power State Transition Latency Tolerance" -- set it to 15 on the active power plan for all drives and see if that helps.

I'm on a bit of a stutter hunt on one of my systems myself so i'll post here as I find things.

fwiw, I have an MSI B550 board, Ryzen 5900X, Geforce 4090 (had an 3070Ti before, but same issue) and I think same SSD as you. Most games have "periodic" sub-second freezes (every ~10-20 seconds), some games work okay-ish, some are basically unplayable. Tried a bunch of things also suggested in this thread over the last year (HPT etc.), but about ready to throw it into the trash and just get an intel system...

have you tried fixing the nvme latency as above? This was a common bug with crucial nvme as well.

NVME Power State Transition Latency Tolerance - was set to 200ms or 100ms instead of 15 and it would stutter as the drive switched power states.

I haven't tried that so far, but will do on Sunday/Monday and follow up here, thanks for the suggestion.

It looks like this for me, im using the second power plan should i put the checkmark in there and still set it to 15?

Are you running your games in full screen mode or board less windowed mode?
I had an issue with No man's sky running in full screen mode and setting one the V-sync settings in the Nvidia control panel gave me stuttering. Changing the setting back to default fixed that, but so will just running in board less windowed mode. Nothing else would remove the hiccups. It would be running a 16ms on 60fps then a 23ms hit ever 5 seconds.
 
you can also try turning off vsync globally in your gpu driver software, force it off globally. then rivatuner with a medium hook set it to your monitor refresh rate (so that freesync still works the entire time)

this is what I do anyway, and never had any issues.
