There was no Update on the 26th. MSFS always checks for updates on startup and maybe that is what you are seeing. The latest version number is 1.36.2.0
And typically updates have been released on Thursdays.
Video drivers are paired with your video card, not your game/program. There is no such thing as a FS2004 video driver, just like there is no such thing as a P3D video driver. So make your changes in your Nvidia Control panel.
Checked NWS and for the past 3 days there has been no snow in Denver and temps above freezing, I have some light snow on the Rockies using real weather. But then again I use REX AccuSeason.
1. You can speed up flights just as you can in FSX.
2. You can save a flight just as you can in FSX, but not every piece of data is saved just like in FSX.
3. Because FSX is old computer code and MSFS 2020 has been re-coded from the ground up.
You can save plans as much as you want, but you need to understand what is saved when you save a flight plan. No, saving a flight plan does not mean you can resume that flight where you left off.
