I run almost anything available for the last 20 years...
In my house:
I have a gen2 iMac that runs either Mac OS 9, or OS X 10.4 (Tiger)
2 eMacs running OS X 10.5 (Leopard)
A 2006 iMac, running Snow Leopard
The 2008 MacBook, running Leopard, Lion, or a hacked Yosemite (depends on what I want to do with it) That MacBook can't ever go to Mojave. It just barely works with Yosemite, which isn't supported, anyway.
(Forgot a Titanium PB G4, running either Linux, or OS X 10.5.8, rarely used)
Main Mac at the moment - 2012 Mac mini/16GB ram/SSD. Runs Mojave very nicely, but I have 4 other systems that occasionally are booted on that mini, 10.8, 10.10, 10.12, and of course 10.14
I run a small Mac repair shop, so sometimes I have one or two other Macs in the house, depending on the day of the week.
So, I can boot up and run virtually any mac OS, which I do something like that almost every day.
Oh, 2 of the Macs have Windows 10, and I have one that can boot to Windows 8 - should I have some need like that.
but, all off subject, eh?
I guess by "seamless", you mean smooth movements? You could probably go into mouse settings (or the trackpad settings in the Boot Camp control panel) to see if changing acceleration - or other cursor speed settings - help in any way.
But, it's still Windows, after all. And, there may be something else than the trackpad++. I have not ever looked for anything else.
I will say that anytime I boot into Windows, I plug in a standard USB mouse, and use that, instead of the trackpad. I care little about the gestures in Windows anyway. The mouse simply works better -- for me...
