appinfo.vdf diskwrite causing stutter

[Hazardous Killer]

Hey, just wanted to make a post about this. Seems I've only found a few posts about this that was apparantly fixed back in 2019. Roughly every 15 minutes an update is pushed for the appinfo.vdf and if you have a large library like me, it causes a 150ms stutter in majority of my games. I've been having this for a couple of months, I've tried pretty much everything to fix it, even though yesterday I found it's only my steam games and client to be the culprit. Is it just an issue on my end or has it popped back up again? NVM/SSD/HDD all do the same thing. Playing offline never happens because Steam doesn't push for an update of the file.

I posted this report about it back in 2019 and yes, it has reappeared for me as well

i also have this issue, though my stutters are a bit smaller, (depending on the pc from 90-125ms) and i also made a post about it before i saw your post.

i hope they fix it, since it is super annoying

Wow and that's happening with 800 games? That's pretty bad... No idea when we can expect a fix though since it's barely talked about.

Going on 4 months or so since the bug was re-introduced. I'm not confident that Valve is even aware of its existence.

i think i found a workaround you can make to the stutters using the steam console:

open steam console by pressing windows+R, typing steam://open/console

type either:

nProductInfoUpdateInterval 0
or
nProductInfoUpdateInterval 2100

the number is time in seconds between updates, however using 0, while it does completely eliminate the stutter, makes steam use a small amount of cpu and network. the 2100 setting has no impact on performance. the max you can use before it breaks is 2100 (35min). default interval is 900

you can also force an update whenever you want, (this also resets the timer) by typing in

update_app_info

you need to do this everytime you restart steam

I tested it with wireshark and it seems to work, but i can't test it in any games right now

Typing this command results in an error for me: "command not found: update_app_info"

Do you get the same message?

Nice, I found the nProductInfoUpdateInterval "fix" a while ago by myself but didn't know what the cutoff point until it broke.

Works fine for me.

Seems you have it back to front. It's app_info_update

Unfortunately the timer adjustment is less effective the more games you have in your library. I'm past the point where any time adjustment at all works - anything higher than default essentially breaks the client and makes the lag constant.

It has.

Or seems to at least. Possible certain users are still afflicted, for unknown reasons.

Oh ya, well that's true but I am going to say that for 99% users I'd imagine it's fixed including Slunkee here. Feel free to post otherwise if not the case because I remain curious.
