AMD Isolates Windows 11 and Windows 10 Performance Stuttering Issues to fTPM

Hi,
What on earth could the calendar be doing to cause stuttering :eek:

Unfortunately that's not the case. Enabling discrete TPM without such a module installed results in the bios resetting itself to fTPM :-(
That's my experience with an Asus TUF Gaming X570 Plus Wifi, so I would be glad to hear about other options to disable fTPM.

That's interesting. That's not what it should do by the description, but I'm sure at least for your board you are correct.

Something related to authenticating the user, is all I could guess. It all goes back to the root of trust established at install time. The better question here though is indeed WTF the calendar cares at all... it's not like we really need harsh user authentication there.

My best guess is that the calendar data is encrypted for privacy reasons (could contain events and appoinments, etc), and thus you need the TPM to access it, but that's just spitballing.

They did? My ryzen x570 board still has CSM.

Same. All Zen have UEFI with CSM.
If you have secureboot enabled, CSM gets disabled.

Not here it doesnt - have you tried clearing the TPM keys at the same time?

Can someone with an un-modified W11 install, verify what happens when:

1. fTPM is disabled
2. TPM keys are cleared (They can be re-loaded from the CPU safely)

I know that disabling secureboot ends up in errors, but i never checked the others before using rufus to mod my installs.

I did exactly this just the other day, if your drive isn't bitlockered pretty sure it just boots. Probably stops upgrades though.

Apparently if you try to switch to discrete without a TPM module the BIOS switches it back, well that at least is what I seem to have run into on my ASUS MB, and apparently an internet search shows others having the same results.

Nothing to complain here, works like a charm. R5 3600, B550 & Win11 Pro

For me it works perfect on Win 11 Pro. I have R5 3600x all clocks oc-ed to 4,3 ghz , MSI B550-a Pro, 16gb ram 3800mhz (16-18-18-18-36), MSI Mech 2x oc (by me clocked till the end) and the A.70 UEFI version
