guaranteed placebo. it will "be back"
Not placebo.
Placesbosplaining without a thesis-style reply is well known to be bad etiquette on Blur Busters Forums, because we science-out those ever-tinier milliseconds... At which point, a thesis-style reply with equations, ceases to be placebosplaining, and becomes worthy of peer eview.
Now that being said.
I've witnessed bad motherboard audio drivers adding milliseconds of lag or lag jitter.
Doesn't mean sometimes you mis-troubleshoot (blame audio when it's not the fault). But I've seen audio be the FAULT of latency before.
It's definitely happened (confirmed). Surprisingly more common than "ultra rare". I'd wager it happens to more than 1 in 100 users, because they're using a specific motherboard model with very crappy motherboard audio drivers, even for Realtek audio. Sometimes even changing the drivers (the microsoft driver versus the vendor driver) actually makes a difference.
Concurrently, audio enhancements execute software-based stuff in an audio driver that can block other things going on in a computer, adding weird latency effects (e.g. delayed mouse reads = weird mousefeel during audio). So that's another cause of audio-lag problems.
It might not have been the cause of your lag problem.
And it is not the only cause of lag (you might have other causes of lag).
But multiple inefficiencies concurrently occuring with audio (crappy audio drivers + bad motherboard model + software-based audio enhancement) has been confirmed cause of some other peoples' lag problems.
And Windows Update may automatically overwrite your audio drivers if you don't watch the audio driver version -- you can avoid the "it will be back" problems that way -- for the audio section of your multiple causes of lag problems. Reinstall your favourite no-lag audio driver or settings. Duh?
Other causes of lag problems will remain extant, but at least you've covered your audio ground.
And yes, there may be placebos elsewhere -- if you will, "placebo" can be part of the whole long latency chain (har har) -- but it ain't the audio if there was a real problem there and you fixed it.
Yes, yes, your average latency might be unchanged, but your latency-volatility (standard deviation) may be terrible (bursty mouse polls) -- latency jitter is evil. Like how a mouse cursor sometimes becomes jumpy (especialy software-based cursors) when the computer is under great load. And you know, at 360Hz, the milliseconds are WAY more noticeable than at 60Hz, since 1ms of 1/60sec is tiny, but 1ms of 1/360sec is a much bigger interference. The higher the Hz, the more the tiny-lag problems become feelable/annoyable. What was placebo at 60Hz cease to be placebo at 360Hz, y'know.
I've placebo-mythbusted enough to eventually put posts into manual-approve if it contains the word "placebo" -- I might adjust the word filter to force manual moderator-post-approves everytime someone mentions "placebo". But I'd also add "EMI" to the same redflag list too, due to useless chases from the wild geese & red herring overpopulation. But in fact, audio efficiency issues is a vastly much more common latency-consistency contributor than niche things like EMI.
After, we're Blur Busters, we found things that matters when others didn't believe it did. Like worthiness of 120Hz and 240Hz, to people who couldn't believe 30fps-vs-60fps.
So we need massively more explanations, like a Blur Busters Wall Of Text or Research Paper, to reveal statistical likelihood of placebo vs genuineness. We're the temporal business (GtG, MPRT, lag, VRR, whatnots). Y'know, that sorta stuff. That's why we're haters of "placebosplainer posts", even if it's a 10% or 98% chance of placebo.
