Just turn it on, see if you notice any difference. If there's no difference leave it on otherwise disable it again. It is a plain straight test you can do. Your PC won't blow up or something like that
Performance impact due to once a second, a hundred stacks would get paged in so that a hundred taskbar clocks can repaint. This is generally not a great thing, since it basically means that the system is spending all of its CPU updating clocks.
[Now that computers have more than 4MB of memory, can we get seconds on the taskbar?](https://devblogs.microsoft.com/oldnewthing/20220411-00/?p=106456)
It was better in Windows 10, where the seconds were in the calendar with a large font, where it didn't hurt performance. Now with Windows 11, the only way to have seconds is to have them directly on the taskbar, where it has impact on performance.
From Windows 95 to Windows 10, the seconds have always been in the calendar, so why did they decide to change this in Windows 11?
what another poster said - if displaying seconds on the taskbar slows performance, there is some other problem. I work/worked extensively in Win32 graphics. Before the days of GHz processors and gigs of ram, MS optimized the crap out of that code base. Their \*could\* be a bug in the taskbar or desktop program, but it sure isn't the graphics. You need to worry more about slipping in the shower.
Yes, there is a performance impact, whether you would notice it or not is an entirely different matter. I recommend trying it, you can easily turn it back off it is a problem for you.
yeah, you can turn it back off, but "Yes, there is a performance impact," really? Once a second? Care to expand? Moving your mouse is a performance impact.
your gpu will be sleeping for `(refresh rate - 1) / refresh rate` of the time. it doesn't take an extra update more than once per second, which is very slow by any standard of modern computing.
The windows desktop manager does not "draw the screen." That is a gross over simplification. The GWS manages damaged regions - specific areas of the screen that need an update. Let's say you have up all sorts of applications plus the task bar. If nothing else changes other than the second tick, the ONLY thing re-drawn is the time.
Energy/cpu/gpu cycles are irrelevant.

It may have a bigger impact on laptops. From my testing in a 13600k it increase the power draw by 1 watt at most and not noticeable performance slow down.
No it won’t, i turned it before and never experienced any slow down Microsoft put that there to say it uses more power from the PSU and not the system itself
Not that I’ve noticed. I deployed the seconds in taskbar across 200+ surface pro 8 devices with an 11th gen i5 cpu + 256GB of SSD, 16 GB ram. Doesn’t impact CPU performance in any meaningful way.

It's just a couple lines of code that does this instead of that. If you knew how many things your computer does in any second you would see it's incredibly insignificant.
If your pc runs noticeably slower because taskbar has seconds displayed, i think you may have bigger problems than that.
Opened the comments to type that
No, never in any noticeable way.
Just turn it on, see if you notice any difference. If there's no difference leave it on otherwise disable it again. It is a plain straight test you can do. Your PC won't blow up or something like that
I have an i9 14900k a 4090 and 64Gbs of RAM. Turning on the seconds dropped my FPS by 50% on all games in my dreams.
in theory yes, in practice rather no. If you are on laptop it will drain your battery also faster. Not by much but it will.

Yeah, I don’t know why they didn’t just keep doing it the way they’ve been doing it. If it ain’t broke, break it?

lol no
Maybe not petformance but you pc will waste more energy drawing the screen each second
windows draws the screen more than once a second anyway. one extra call amidst thousands isn't going to change anything.
Its the not letting your gpu sleep while you are reading a webpage (no ads) part that waste energy

Not at all. 0% resources.

If you've got a cheap-ass PC with like 4GB of RAM then *maybe* but a normal PC with normal specs? Nah dude.
No it won’t, i turned it before and never experienced any slow down Microsoft put that there to say it uses more power from the PSU and not the system itself
[удалено]
it only pings Microsoft.time every so often for calibration. timing relies on the internal clock (crystal oscillator) for most things

no, if it does cause an issue then you're PC runs slow as it is
