1809 versus modern versions could be placebo effect without any data to support it, and you could be wasting not only your time, but our time too as we troubleshoot your images. What if you find out 1809 is worse in comparison after you spend forever making a preset designed for this old version? It's better to spend a few hours researching this first.
I know it might seem odd to some people since I advocate for an old version too (21H2), but that was because 22H2 initially had numerous bugs at release and it took until about the end of July for Microsoft to iron most of them out on W10. I was not on W10 when it evolved from 1607 to 1903 (give or take), but I have read countless forum and website posts discussing that popular "gaming" period, and from what I can gather there was several huge performance bugs that exist in that era which were later patched out, including memory leaks.
I'm not saying that older versions don't perform better, but there really needs to be some kind of verification. This is why there's so much misinformation on the internet because the masses assume too much without any actual testing. Also, some anti-cheat providers and developers are removing support for older versions of W10 and you cannot run their software on those versions (
