So, I've done some flying after installing the patch. Here are my findings:
Microsoft needs to find a better way to download and install the patch. I launch the sim, it says I need to open the MS Store app to download the update. Before I have a chance to do so, the MS Store app launches automatically (thanks, I guess?). Then, once MS Store is done, I launch the sim again, which then begins the process of installing the patch. However, judging by my internet activity, it seems that what's happening is that it's downloading the patch...again.
Anyway, despite reports of the latest patch totally breaking the sim for some users, I can actually use it for it's intended purpose: converting me to a nearly total social recluse.Performance Improvements
The stuttering I observed while the sim loaded new scenery is now nearly totally gone. This apparently was caused by the refresh rate on the "glass" avionics. MS/Asobo added an option within the menus to adjust the refresh rate. Medium is the default and seems to work quite well.
There was talk of reducing the opening credits sequence to increase start up time. All that I noticed was that the "Powered by Wwise" screen no longer appears. Personally, I would have removed the "Press Any Key To Start" but I'm no coder.ATC Updates
The added some new voices to the system, so there is a bit more variety. Unfortunately, they didn't see fit to address actual user complaints like phraseology, the AI ignoring requests for different approaches, etc. Just new voices. Oh, and some of the voices can't say "One" and instead refer to the numeral by spelling out the word O N E.
It does seem, though, that the real world flights are no longer harassed to descend to 10000. They do say they are descending though, when checking in.
Not sure if model matching has gotten better, but the sim ATC still thinks that A320s are sometimes "Heavy" and when giving traffic warnings calls them A20Ns.
Landing at KAPA, traffic ahead of me was told "position and hold." The AI aircraft then apparently just took off as ATC kept saying "you did not have permission to take off." It did that a few times before terminating it's IFR clearance. I've never experienced that in this or previous versions of FlightSim.General Aviation Avionics Updates
Other than the refresh rate issue, I see no real updates in the sim (C208 and TBM). I do know that using FLC in the 208 will cause a stall as the autopilot pitches wildly up. Oh, also in the 208, the autopilot will kick off while flying an approach and will not turn back on. Those two issues weren't present pre-patch.
Still no "Track Up" option nor can you deselect Topo.Live Weather Updates
Pre-Patch, live weather would get you everything but the wind. The wind, at least in the US, was always 225@3. Now it works. However, it doesn't display properly on the Garmin MFD (the PFD display works, though).
