What's special about winver 1909?
So i wanted to get forza horizon 5 , but I see it needs minimum win10 1909... i don't have that (i have 1803) and I also read they're serious about that, there's no known workaround to make it work with older versions. Ok, then I checked on my laptop (its too weak to run it, but i thought I'd check anyway) and that is on 1903... Now you'd think just update, right, but i can't, i already tried on desktop and laptop, it makes both basically unusable...on desktop it just feels sluggish, but also about halves my fps in games (tried several, even 1903 does that on my desktop) and on my laptop there goes nothing, sound stops working, explorer is slow as hell, games run at 1fps, i also completely loose full rgb monitor support, but that's the least of the problems I suppose... I'm just wondering (triggered by this weird fh5 requirement) what does winver 1903/09 different than say 1803??? There must be some big under the hood changes? Desktop specs in profile, laptop is i5 7200u 8gb ddr4 940mx 2tb hdd (and everything runs well on 1903, except the karman sound, which has been lost in an earlier update, the sw is installed, its just not working) So the 2 machines are completely different, but both have massive issues with winver 1909... Just curious, and a bit disappointed i can't play fh5 on either system... Edit: so the only things I'm seeing that seem important with 1909 are "virtual desktop" "sandbox" and "core optimization"...? doesn't really make sense any of this would have such an effect... yet something does.
There are no major updates since May 2021. The system remains stable with no significant changes. All Windows 10 devices supporting 1803 can also run 1903, 1909, and the newest version 21H1.
There are three distinct systems with varying opinions. One struggles with Windows 10 after 2004, though it functions, while Win 7 and Linux perform better. The other two are newer, Ryzen-based, and still in the process of understanding them.
basically, it’s like moving from an older version of Windows to a newer one. Version 1803 and 1903 are similar to upgrading from Windows 98 to XP or XP to Windows 7. Version 1909 is like Windows XP with the service pack 1. Version 2004 is about moving from Windows 7 to Windows 10. I’m not totally precise, but that’s the general idea.
I think the important question is why are you running a 3 year old version of Windows. Are you aware that you stopped receiving security updates 2 years ago? Just update the damned thing. ok i see that you got a massive performance drop when updating but there is no logical reason for that. Have you done a clean install?
I'm curious about whether this setup resembles an outdated Windows experience. Previous versions that received numerous updates over time can occasionally become unstable. I don't understand why or how to resolve it beyond a complete wipe and fresh installation. If you have extra storage available, consider performing a clean install of the latest Windows 10 to check if issues persist. Running on a very old motherboard likely isn't ideal. Have you checked for updates to the chipset drivers? The "Favored CPU Core Optimization" setting we've observed with Windows 11 suggests an OS-platform interaction, making chipset drivers relevant. This shouldn't be an issue on a laptop unless you're using a specific CPU model—there doesn't appear to be any indication of such a feature. I'm unsure if it impacts other Windows releases, but enabling HPET might lead to performance problems.
It's a possibility that has been bothering users since early versions, like XP and Vista. The update process on my laptop wasn't that old—just a few months ago I upgraded to 1909. It seemed to work better with Windows 11, while the same laptop ran smoothly on Windows 10. The RGB display and audio quality improved too. I might consider a fresh installation on my desktop later. It could be that my PC resists this "core optimization" change, possibly due to driver updates or a recent BIOS update. I'm pretty sure I've already updated my BIOS, which likely affected the CPU settings. It's unclear what this change does, but it seems similar to the effects of service packs I used before.
It seems LODCTR and LODCTIMER are related but distinct. LODCTR is the default timer, while LODCTIMER is a different variant you might be using. The performance difference you noticed is likely due to the settings or configuration differences between them.
