Well, I figured it would be a mad house download grunge party on the first day, especially for any new and popular PC game or sim (have to remember that MSFS has millions of users as compared to combat flight sims), so I studiously avoid even trying to DL and install for a day or 2, or 3. I do the same with MSFS updates and even my IL2 Box updates as things always go more smoothly if I wait till after the gold rush.
Expect some bugs, but some of the early comments I've seen already are pretty positive. Some devs have also already noted where there might be some bugs in 2020 addons, but even some of those aren't to bad, or as bad as expected anyway.
I've also been taking the time to do a little homework on optimizing for 2024 before I DL in the hopes I can forego some issues. All in all I'm looking forward to some fresh bush flying next week.
