This is a little late but have you tried running more than one hard drive on your Windows 10 pc? At one point I had three, one with Windows 10, one with Windows 7, and one with Windows XP. 7 and XP require doing a little research and figuring out how to get them to work with a modern pc but they do, or did, work. I run XP so I can play War In The Pacific: The Struggle Against Japan the Matrix game and it runs well on that. I'd give the hard drive dedicated to only XP a try. I was in a CFS2 squad 15 years ago and we had carrier ops, navigation (CFS2 as with the civilian versions of MSFS has the whole world modeled with the correct lat and lon and you can use trigonometry and rhumb line calculations) to plan flights, attacks, and egress back to land on the carriers. We even had modified B25's with tailhooks so we could enter multiplayer, land a number of them on a carrier and taxi to take off position, and then launch the DoLittle Raid. We actually flew for 7 hours one time to recreate that attack on Japan by DoLittle and his pilots and then flew on to China.
