One thing that helped for me was to treat MSFS 2024 as an entirely new, different flight sim and approach it as I was learning how operate it from scratch. Now, they don’t make this easy because there is a lot that is not explained well.
But the other main thing is that I am just naturally much more forgiving of imperfection than most simmers are. This comes from my history with the most basic sims up to today’s offerings. I can focus on the core aspects and ignore the details that don’t work.
Some things like control setup was tedious and confusing, but over time, I feel that I have a good handle on how it works. A gotcha is that some types of aircraft have their own dedicated settings, so the first time you fly a glider, the existing controls you thought were configured need to be done again.
What works in my favor is that my typical flight sim sessions are VFR with fairly simple planes and I prefer the low and slow, stick and rudder work over playing with the technology of the avionics. When new freeware planes show up, I don’t care so much about visual fidelity or systems as long as they feel good to fly.
In fact, I think that the flight model improvements in MSFS 2024 have been an enormous step up and I tried some of the same conditions in 2020 to confirm it. This alone make me much more likely to choose 2024 for most flights. But again, this aligns with my personal preference, so others may have different priorities.
Performance has been much better in MSFS 2024 for me after I had turned down many graphics settings. It still looks very good but I seem to have found a sweet spot. I think that the bandwidth limits are useful for consistent performance. Signal to the sim to not try to stream more than can be handled, not what you think should be your maximum possible bandwidth. I suspect that some people that have performance issues have hidden bottlenecks that are making their experience worse.
