And there are many simple workarounds for this - just search the forum. Annoying? Yes, but you can complete a flight - I do every time I fly.
It is sad there was no mention of the freezing stuttering issue. after the last update I did a test flight from sarasota to ft Myers In the g36 and got severe stuttering and freezing all along the way. This is a area I have never had performance issues In before, and with a GA aircraft, which I never get performance issues with. And it wasn’t just approaching an airport, it was flying along over a sparsely populated area at 5000ft. Boom. Out of nowhere, sim becomes a slide show. It didn’t last a few seconds either, It went on for minutes and I had to quit the sim. This was with mods in the community folder and without mods in the community folder. No difference. Glad to see I’m not the only one with this problem.
That is a wild level of detail!
The video said that they had found two issues/bugs relating to performance that effects certain hardware combinations, which is why some people see it and a lot do not. They were debating on doing a hotfix to address the issue, depending on how bad they see it from feedback.
The devs and testers did not have the specific hardware configuration, which is why it was released because all tests looked good. They are rewriting parts of the system to reduce memory footprint which allows the system as a whole to run better and they said around 1500 tests applied and all had improvements.
I’m at unusable status right now due to CTDs and stuttering in VR. Too many new problems to even list here, also. I’m sure it will be fixed, but another day forcing me to go read a book or something. lol
Yet people reporting issues and listing their specs are showing a wildly various systems. Anything and everything from 5th to 10th gen Intel CPUs, 1st - 5th gen Ryzen, nVidia 1000-3000 series, AMD 500-6000 series and everything in between. Bascially, any hardware made in the last 5 years. Which is basically what’s realistically required to be able to run the sim at all.
It’s not an issue with specific hardware as they alluded to in the Q&A.
Second that. I think that was a statement to appease the affected and calm the conversation. Maybe they have identified something. But by the looks of it it’s not at all what everyone is talking about since the last Update.
It’s more than 1 issue. The UK update caused a massive performance hit to some people as well and there’s a full thread in the bug section describing it. That caused me to go down from 45 to 30 fps. Whatever happened in the last sim update aggravated that even more for those of us already suffering form the issues from WU that were never addressed. Now I and many others (regardless of their hardware) are sitting at fps levels in the low to mid teens, essentially rendering the sim useless unless someone likes looking at Powerpoint slide shows of airplane cockpits.
The thing that annoys me is that at least publicly the devs seem so nonchalant about it. “Yeah…we might do a hot fix…”.
If we were enterprise customers going through critical issues I doubt they would be so relaxed.
Enterprise customers have ongoing contracts. The company gets ongoing payment for doing work.
They already have our money.
I always thought that a hot fix was for something you did not plan on breaking but did which this is.
The frame rate limiter has stopped working, also I noticed ai aircraft are appearing/spawning much closer than before the update, there are no ai aircraft more than about 4 miles away.
Realizing that CTD discussion is the hot topic at the moment (and I just fell victim to it big time, I thought my computer was lost (SSD’s weren’t recognized after forced reboot after stutter to a stop after passing by Heathrow)), anyone else think it’s kind of funny that they’re going to fix the freezing issue this summer
“Hey, look! They’re not freezing anymore!” 
Sorry, I giggled on reading it 
Disclaimer: I’m not a real world pilot, aerodynamicist and do not have either JF Arrow or Flying Iron Simulation’s Spitfire for MSFS yet (waiting for their arrival in the marketplace).
Yet many pilots, including commercial pilots and CFIs who tested JF Arrow and others such as Carenado PA44, are quite satisfied with the amount of adverse yaw most of these planes generate. I’ve been told by pilots that two C172s might exhibit totally different amount of adverse yaw, depending on a lot of things. Most pilots who are also simmers tell me that adverse yaw exists in MSFS, but it’s a bit on the ‘weak’ side, and should be looked into by the core sim devs. However, Carenado cracked it very well, and in their PA44 you have to apply a considerable amount of rudder to make coordinated turns, specially at low speeds. I was also watching a FSX A2A Comanche stream last night where it exhibited little to absolutely no adverse yaw during gentle turns.
The developer said, and you quoted:
Perhaps the developer needs to consult with Flying Iron Simulation developers. More on that later.
Here are some demonstrations of JF Arrow’s stall characteristics done by a real world flight instructor, commercial pilot and Q400 first officer, who also has more than 200 hours in Piper Arrows in real world (first forwarded to the point where it starts):
In brief, he says: “Stall characteristics are bang on the money. This is the exact behaviour a real world Piper Arrow would exhibit during stalls. This is the best representation of a real world Piper Arrow you could get in a home desktop simulator. It exhibits “book” numbers at all times.”.
This I’m not too sure, as the pilot in the video above didn’t do this particular manoeuvre, nor did I find any video demonstrating it. He did a 45 degree steep turn demo though, and was happy with what he saw.
In conclusion, he claims the JF Arrow is the most book-accurate plane he ever used in a simulator.
Let’s move on to Flying Iron Simulation’s newly released Spitfire for MSFS. Why do I think it’s important?
Stormbird (his pseudonym) who’s been using flight sims (specially combat flight sims) since the commodore 64 days, has flown the study level Spitfire in DCS World for approximately more than 400 hours, and has been doing reviews of various combat flight sims on his blog since 2016, had the following to say about Flying Iron Simulation’s Spitfire for MSFS after comparing it with the study level Spitfire in DCS World (and another one in IL2):
-
“Takeoff run, with trim set, is more similar than different across all three Spitfires” in other sims.
-
“Once cleaned up from takeoff, I can say almost immediately that this aircraft feels very familiar. It’s a type that I feel very much at home with in other sims and I had the same feeling here too.”
-
“With many hundreds of hours on the IL-2: Great Battles Series Spitfire IX in pitched multiplayer and single player battles and at least several more hours on the DCS: Spitfire IX, I can say that all three feel about the same while cruising along and while using the controls in cruise. The Spitfire is noted for being light on the elevator and heavier on the ailerons and you can feel that here”
-
“Landing here generally feels very good too. The Spitfire in all sims remains controllable down to near stall speeds and my almost instinctual nose up trim use came in use here as the speed bled off. There’s also an immediate nose down movement when the landing flaps are deployed and the experience felt the most like the DCS Spitfire IX. Touchdown feels like the other two Spitfire’s and is generally predictable unless too much power is applied.”
-
“Roll out after landing is very similar to taxiing with this being the easiest of the three”.
-
“Excellent visuals, strong sound effects, and a good flight model on the whole makes this an excellent aircraft to fly and a challenging warbird”.
-
Some of the systems and failures are not simulated yet (due to limitations of the current SDK and not MSFS). These issues and limitations are very minor and “well within the (development) team’s grasp”.
In conclusion, he says that when it comes to the overall flight model, apart from taxiing behaviour on the ground, everything else in FIS’ Spitfire in MSFS feels exactly like how it feels in the DCS World Spitfire addon.

My point here is not to say your criticisms are invalid, nor am I challenging them. Nor am I or the more than 96 percent of flight simmers who never flew a plane (according to the very latest Navigraph survey) are qualified to do so.
My point here is to present some facts, and reviews that I collected from real world pilots, and offer my two cents: Nothing in the world is set in stone. No one flight model of one single aircraft is set in stone, in either real life or a sim. Developers disagree with a lot of things, so do flight model specialists, scientists, and pilots ( two examples: https://twitter.com/JonDopplerWX/status/1370185416930959364 and https://twitter.com/aviatorwriting/status/1370990615584907265 )
The JF Arrow developer/s might need a bit more education on how to work with the new MSFS flight model and SDK? or may be they don’t (cause the flight model they developed so far is “bang on the money” by some real world pilots?) ?
Six months after release, Flying Iron Simulations develops a flight model of the Spitfire in MSFS that accurately resembles that of a study level Spitfire for DCS World? How could that be, if the MSFS flight model was so bad, and “there is a disconnect between what Asobo are seeing, and what other people are seeing, including developers with 25 years of experience.” ?
Does this mean not all 3rd party aircraft software developers are equal? 
In the words of Matt Nischan, one of the developers of Working Title Simulations:
There’s no conclusive observation that can be made by looking at one specific aircraft flight model configuration and then applying that conclusion to the entire flight simulation. How well a particular aircraft meets book values is entirely dependent on how well the flight model author adjusted the values to make the book values possible.
In the right hands, the MSFS modern engine is going to produce some seriously accurate aircraft. How do I know that? Because our Working Title CJ4 does actually hit those book values at all regimes, with correct N1s, fuel flow, climb rates, over various altitudes and ambient pressures. Not only that but we have stall speeds within a knot of two of book, proper approach angles, correct bank rates, etc.
Thanks for the very detailed reply. If it is indeed the case that the reason for the JF developers’ remarks is that they just haven’t learned how to use the SDK properly, then that is good news for everyone. I have to say that I’m doubtful that it is as simple as that, but I am not qualified to make a judgement.
There have been comments by equally well-qualified pilots, for example, the Corporate Dad on this forum, that the adverse yaw is little or non-existent.
Reading the JF developer’s remarks, I had the impression that he had fed in the mathematically correct coefficients into the model, the same coefficients that he used in other sims, but the results were not what he expected.
That kind of ties in with my remarks about what Asobo is seeing being disconnected from what others are seeing. The most surprising thing to me about the last feedback video, and about Asobo’s approach in general, was that the CEO of the company personally made a few short flights to check various features of the flight model and concluded that everything “seemed okay”. Bear in mind that Seb has little flight sim experience, and is not an experienced pilot.
I guess what I was hoping for, and expecting, is that they would have a much more rigorous and clearly defined testing regime and that they would be in a position to be much more definitive about the flight model: “We are certain that our flight model is mathematically very accurate.”.
I thought they would be able to say, definitively, exactly what adverse yaw to expect from any given plane in any given flight conditions. That is what they seemed to me to be saying with the advertising videos showing the thousands of points of measurement on the wings.
I guess if it were easy to create such a mathematical model, they would have done it already. Absent that, we are left in the position of having to find YouTube reviewers who subjective opinion we trust and to take their word for it.
At the end of the day, it’s still a wonderful sim. I enjoy using it and I’m sure it will get better over time. I do have a niggle at the back of my mind that in several respects the realism is not what it might be, and that Asobo/MS, at least in the early phases of development, were not giving realism the highest of priorities, and were perhaps not fully aware of its importance to many simmers, but in the scheme of things that niggle is insignificant compared to pleasure to be had from flying the sim.
The SIM keeps crashing. Anyone else having this problem? Anyone have a solution?
