Random pauses in AH--a clue

[Drano]

I've posted about this problem before. I've been digging around trying to duplicate the problem forever. Over a year certainly. Can never pin it down. Game hiccups for a sec, might do it twice in a row. It seems to manifest itself in AH more than any other program I use. It would affect my controls mostly. I'll see a micro pause on the screen and my controls would get screwey. Most often my throttle and RPMs would go to half. I have a CH throttle and Logitech quadrant for those. Worst of it---I'd get that controls unmapped thing. REALLY annoying during a frame of FSO. This problem seemed to evolve over time. It started as a slight glitch to that unmapped thing. I've read about USB dropouts with X570 boards (which I have) but this isn't really happening. I get no actual disco of USB. Nothing shows in USBeview. Nothing in windows error logs. Really hard to pin down or duplicate. Pulling my hair out over it. I've updated my BIOS with each revision and that's where I think the evolution of this problem is tied to. It got worse each time until the most recent BIOS and now it's back to the just moderately annoying burp and throttle/rpm thing. Moderately tolerable but it'd be great if it'd just stop!

I'm on a google hunt the other day looking for bread crumbs. I run across this: https://www.tomshardware.com/news/amd-issues-fix-and-workaround-for-ftpm-stuttering-issues

Check the short vid on the page. This is EXACTLY what's happening to me. Stupid little hiccup. I have an ASUS X570-E mobo. Apparently it's some memory thing with the TPM chip. Which explains why I never got anything that rhymes with an error or disco. I never had TPM enabled in the first place. The latest BIOS I'm reading, has firmware TPM (fTPM) that's included on the CPU enabled by default. Checked my BIOS settings. Sure enough, it's enabled now. I'd read it'd be better to use a discrete chip and use dTPM so I grabbed one of those. Haven't installed it. Because since then I'd read that the fTPM setting in this new BIOS will reset itself to enabled after a reboot putting it back to fTPM instead of dTPM. Brilliant! It's a getting ready for installing Win11 thing. Which is also not imminent with me. I just want this micro pause thing dead!

Anyway, just passing this along in case anyone else has an X570 board that acts a little funny. I've been searching for clues on this for a while.

The linked article says that the long term fix was supposed to be a BIOS update.  Have you checked to see if there is a firmware update for your motherboard?

ETA:  If you have the "ROG Strix X570-E Gaming" motherboard, then there was a bios update published at the end of May specifically to fix the fTPM stutter issue.  If not, then check the support page for your specific motherboard.

BIOS v 4403 for the X570-E Gaming mobo is linked here:  "https://rog.asus.com/us/motherboards/rog-strix/rog-strix-x570-e-gaming-model/helpdesk_bios/"

Yup. I was waiting for it too! It didn't fix anything. Unless by fix you mean less extreme. It is less than the previous version.

Now that I'm on this trail... Heck I thought I was looking for a USB problem. But it's really a TPM problem. I'm finding this has affected an awful lot of boards and manufacturers. Naturally it also seems worse if you have a 3900x. Which.. Hehe.. Yeah.

Either way for whatever reason it affects AH pretty dramatically on my machine. I'll play IL2 and MSFS and if this is happening while playing those games  it's not even noticeable.

Gonna try to disable TPM and see if it changes anything. I don't have anything encrypted and hadn't physically enabled it in the BIOS. Nothing set up in windows either. It's being automatically enabled is apparently a new feature. Didn't fix crap.
