There you have it! Messing with Windows update about a month ago I seemed to set the wheels in motion to go from Windows 10 Pro to Windows 11 Pro. I did some searching to see how I could stop this but to no avail and just resigned myself to the fact that it was going to happen despite the fact that all I was ding was investigating the option. Given it was Windows 10 Pro I could delay the inevitable by 30 days giving the opportunity of investigating how to stop it further if I could find the time. I never found that time and one day I got the notice that windows would update and it did. I Though its not worth the effort to try to stop it despite wanting to stay on W10.

The bottom line is that I am actually astonished that my CPU barely breaks a sweet now running MSFS on Windows 11. Most of the time of the time in GA flight I rarely see the main thread over about 25% except on the ground a destination I see about 50%+. In Tube liners I'm seeing a bit more but defintely much lower than it was in W10 where is could easily see the main thread in the 80's and some times in the 90's on the same flights.

It definitely weird and my perception of performance is certainly far better. I know its not placebo because its a change that occurred against my will so the placebo would have been to perceive a decline in performance.

Whilst I'd love for W11 to offer that kind of performance improvement over W10, I'm going to suggest that there was something else at play here. Perhaps a process running that was incurring much higher CPU time in your previous system install?

I want my main thread running at 90% to produce the best results....what I'd love from MSFS is for that main thread to just be more efficient so it can achieve more whilst running at 90%! 🙂

In any event, good to hear you're happy with the upgrade. Maybe its time I did mine too.

 

Not sure of your system specs, but Win11 is better optimized for the P-core/E-core architecture of the 12th and 13th gen Intel chips. I am sure the same will apply to AMD when they move to their big.LITTLE architecture.

I've been on Win11 since the beginning and wouldn't give up the additional features that have come along the way (Windows Explorer tabs, better task manager, better terminal, and I still want to mess around with the Windows subsystem for Android one of these days). I haven't messed with the Start menu in years as it's usually faster to just hit the Windows key and type what you're looking for. Much of the additional web-enabled features can be disabled easily enough via the local policy editor for people who don't want to be bothered.

I still get lost searching for system settings sometimes, but that is what search is for. At least MS is being more serious in trying to move away from legacy Control Panel functions.

No, I'm seeing what I'd expect to see running with the main core at a such low percentages. The setting are maxed out and I getting over 30fps. I'm using a 10900k at 5.2ghz and a 3090. I'll post a vid wit RTSS to prove it.

No real change in performance here on an Nvidia 3080 12 GB between Win 10 and 11, but MSFS itself does randomly have varying performance partially due to where I'm flying, but sometimes due to server issues or just something running in background on the PC, or occasional but much rarer a memory leak with an addon.

The FPS Min might be slightly improved but the top-end is the same at least.

Not sure what processor you have but I remember reading that Win 11 utilised the features of the Intel12700 + chips better than win 10.

The sim runs fine for me on Win 11. Can't say I've ever seen an OS related problem with the sim.

I'm running MSFS on a fairly old i7 and Win10. I can't upgrade to Win11 without doing the BIOS security trick/kludge (which I know works as I did it on a non-sim PC) ... but my feeling is "if it aiin't broke ..." so hold off until some sort of a disaster forces me to do it. I suspect (as it's an opld CPU) that I'm unlikely to see the sort of performance gains your're getting.

I do like Win11 (it's on my laptop) - it just stays out of the way and does its job (what any decent O/S is meant to do) - but is very helpful when this old brain forgets how to do things.

However - what *does* put me off is the transition/procedure of reinstalling MSFS on the same machine, but with a newer O/S.

Yeah, that statement is most certainly valid. I would suspect so as well (although it would probably be more aptly described as 'nocebo'  😉). 

I don't even remember when I went from W10 to W11. Can't really say if I noticed anything either way. I think I perceived the performance about the same. 

I have not noticed any improvement in performance since switching to Win 11, my cpu runs as calm and cool as before and my fps are the same, I suspect that some setting in windows or bios got right when switching to tll Win-11.

That's my experience too.

Since last year I changed to Win 11 and even tested MFS in DX12, I will not go back, not only for the sake of MFS but also because of that.

It is not only smoother but a lot more stable, and Win11 contrarily to Win10 doesn't suffer from that irritating quirk of becoming net-unstable whenever there's an update waiting to be fetched and installed...

I have never had a problem with Windows 10  being unstable before an update, on a PC at home and 6 at work. 

So many people have moved to Win 11, but no one is describing this kind of a change to main thread demand, at least not at this scale.  I wonder what really caused this, or if the reported loads are correct or valid even.  Red herring for some other factors.  Suddenly, w/ a less than sterling CPU the sim is no longer anywhere near main thread limited?

Yes, you are probably right. I updated RTSS and the picture has changed. Only one test flight into KLAX in the FBW and FSLTL and I'm seeing more like 70 to 80% on the main thread at 30fps. on thing I have noticed before and after W11 update is that the FPS still drops on short final despite the GPU and main thread being well below 100%

I'll try my GA test flight and see if this holds.

But I will say that I do see an improvement in performance post W11.

So may people have moved to windows 11??? According to the latest statistics windows 11 is installed at around 23 % of windows devices/ PCs and windows 10 is installed at around 75 % of them.

Good for you.... With 300+ PCs at work, 3 at home, over different VPNs and with critical aviation weather on it, sometimes Win10 is a true nightmare for me and colleagues... Usually no more problems once we go Linux or Win11...
