I really want to embrace MSFS 2020. ......really I do.
I have 2 machines that can run it with no problems.
Because of work, life etc I don't have the time to jump on the PC and fly somewhere as I used to.
Every time I fire up MSFS is installing updatess......86 gig here .....75 gig there there. I have 200MBs internet.
The other night I walked away from it and let it do it's "Update".
Fired up my 4 Gen I7 8gb Lenovo laptop and fired up FS9 with all the scenery tweaks and it performed flawlessy.
I also have Xplane, P3d, FSX and even dabbled with flight gear.
Hard drives are relatively cheap and Dual Booting has been around forever. One can fire up whatever OS one wants with very little issues and use the FS/OS of their choice. Get a NAS with rsync and do back-ups of your Hard Drive/OS/FS.
Who knows maybe someday I'll be like "Oh no way.....I am sticking with MSFS 2020. MSFS 2035 is still beta"
Or Sub-Logic FS-2 on my C64 flying from KISP to KMVY....mid flight Loading.....Loading......Loading...
Just my Two-Cents (before taxes)
