I believe that. I’ve been running FS2020 in 1440p for almost 3-1/2 years. Prior to that I was running it at 1080p on my i7-6840 laptop. For me, my money, and the level of effort I feel like going through to optimize and tweak, 1440p is a very strong sweet-spot. 78% more pixels than 1080p, but not as demanding as 4K. When I rebuild my PC later this year (new CPU, motherboard and DDR5 memory), I’ll consider going to a 4K setup. but I doubt I’ll do it. More likely I’d go to a curved 1440p ultrawide setup instead. But that’s a can I will kick down the curb with no hesitation.
So maybe the difference between your setup and mine is that I’m running in 4K. With that said, I also did some comparisons and took some screenshots for comparison.

Conclusion:
After conducting my own tests, my results suggest that the kind of performance improvement you’re seeing is far from universal.
For reference, my MSFS 2020 settings are actually higher than what I’m using in MSFS 2024, yet the difference in performance is marginal at best. Specifically, with the A350, I’m only seeing a 2 FPS improvement in MSFS 2024. More notably, the FSR M500 performs worse in MSFS 2024, with an 11 FPS drop compared to MSFS 2020. That’s a surprising regression rather than an improvement.
I fully acknowledge that performance varies based on hardware configurations, background processes, and even specific in-game conditions. However, your claim of a 115% performance increase appears to be an outlier rather than the norm. In fact, from discussions I’ve seen across multiple forums, the general consensus is that MSFS 2024 offers moderate gains at best, with some users even experiencing regressions in certain scenarios.
What I find especially odd is that, with your system, you were only able to get 60 FPS in MSFS 2020, yet in MSFS 2024, you’re suddenly exceeding 100+ FPS. That’s a massive jump, and while I concede that it appears possible for some users to see near-doubling of performance, I’m not convinced we’re seeing the full picture here. I’d be curious to see more details about your test conditions, hardware utilization, and settings in both versions to better understand what might be accounting for such a dramatic difference. Additionally, the claim from the original point that I made that the individual was running at 30 FPS in MSFS 2020 and are now nearly quadrupling that seems highly unlikely, if not outright impossible, under normal conditions. Even with substantial optimizations, a 4x increase is far beyond what the majority of users—myself included—are experiencing. Right now, it just doesn’t seem representative of the broader experience.
Upthread you argued with another user that his claim of doubled performance wasn’t true. I tested myself and what do you know, with this aircraft at this scenery and on my hardware, with as close to the same settings between simulators as possible, I got more than double performance. So no, I cannot support your position that it’s not possible.
You can believe what you like about “outliers.” Of the anecdotal claims I’ve read in the threads I pay attention to in this forum and on several Discord servers I frequent, substantial performance improvements on FS2024 as compared to 2020 are very common - my system is no longer cutting edge but as a result, I’d say it’s closer to the norm among the flight sim community as a whole. In fact, just this morning I participated in the 2025 Steam Community Hardware Survey - those results might shock you.
In any case, I can state confidently that whatever changes Asobo has implemented under the hood to better utilize multi-core processors; to multi-thread more efficiently and effectively, they work wonderfully on my hardware. It has breathed new life into my CPU and pushed my decision to rebuild my system entirely back by a good six months, time enough to let the supply chain issues with new chips and boards sort itself out and avoid paying exorbitant prices or deal with scalpers sniping inventory.
Until then, I’m done arguing with people telling me or anyone that our results aren’t real.
For a complete picture, could you also add screenshots of your MSFS 2020 and MSFS 2024 settings? It would be helpful to see the exact settings you used while testing A350.
Just do a few traffic patterns in it, let the first one perform an autoland and watch what it does; then on the second try flying with AP until 1,000 feet; and for the third approach fly manually the entire time. I learned to handle this one really quickly that way.

I’m out of the sim for the evening (both of them). But they’re really not that customized. Standard 1440p resolution (2560 x 1440). Antialiasing is set to TAA. For settings, in both cases set to High End. Change Volumetric Clouds to Ultra. Set OLOD to 200 (to help reduce stutters on landing). In FS2024, set Airport and In Flight Traffic to Off. That’s basically it.
I originally disputed the claims of massive performance gains, but in my last post, I even acknowledged that some users like yourself are seeing significant improvements. However, those cases appear to be the exception rather than the rule. A simple search and review of discussions surrounding MSFS 2024s release make that clear.
Dismissing the broader consensus in favor of isolated experiences doesn’t change the reality that, for most users, the performance difference has been far more modest and plenty have even regressed. But if this discussion is just going to ignore that larger context, then there’s really nothing more to debate. I’ll leave it at that.
These are conclusory statements that I cannot agree with. There is no “most users” you are positioned to speak for, nor is there some “broader consensus.”
Neither you nor I are in a position to make such statements with regard to anything; only those with access to Asobo’s and Microsoft’s data analytics group, working from sim telemetry, can know the average performance changes for individual users who have flown both sims, let alone know whether “most” have a small degree of improvement, a large degree of improvement, or a regression. I think it’s quite likely you are seeing what you are preconditioned to notice in anecdotal reports, as probably I am.
But I’ll take 16% better gate performance and 115% better on-the-runway performance on my hardware in this aircraft, and 37.5% better performance in the PMDG 737-800, over anecdotes from others every day of the week.
I was under the impression you were done arguing.
Did something change, or does that only apply when others disagree?
It changes when people post unsupportable statements like “most” and “broader consensus,” when it’s plain that neither apply.
A major factor in the improved performance of MSFS 2024 is dynamic LOD – you likely had this option enabled. However, without screenshots, it’s hard to say.
Dynamic LOD isn’t present in MSFS 2020, which is why MSFS 2024 may feel smoother to you. This feature plays a significant role in performance improvements.
Ah, I see. Well I think we’ve argued this point enough because it’s clear this conversation is going no where. I’ll be the better man here and truly let it go. You can continue to argue with yourself if you’d like.
Indeed. No need for screenshots - as I said, my settings are not that complicated. Dynamic LOD is the default in FS2024, which is what I said to start with. The default target framerate is 30 fps. Above that, it has no effect.
That said, I have used [A MOD WHICH SHALL NOT BE NAMED ON THESE FORUMS] in the past to do the same in 2020; it improved performance in terms of framerates, but not in terms of fluidity and smoothness. My tests today, taken in a static aircraft at the same place with the very same scenery in both simulators eliminates dynamic settings as a factor.
In every case, in FS2024, my default framerate without frame generation was well above the 30 fps floor where the setting would have kicked in.
I’ll check the FPS in my free time, just like you did. It won’t be a proper test - just satisfying my curiosity 
I’ll do “real tests” when I install the G.Skill 2x32GB DDR5 CL26 next week and compare the difference with CL30.

That’s basically how my afternoon started today once I realized I didn’t want to spend the effort to watch a bunch of tutorials and learn how to fly an Airbus for real. I did manage to figure out how to power up the plane, get my Navigraph and Simbrief info into the EFB, update the navdata, and even load the flight plan and load sheet data into the aircraft itself. That’s about as far as I could go on my “Venkman Drives a ‘Bus” tour for the day. I just kept thinking, “If this were a Boeing I’d already be in climb by now …”

I don’t think that’s too surprising, given that the FSR M500 is a 2020 plane. Aircraft specifically designed for the new sim are going to take full advantage of the latest trickery that allows complex aircraft to run better than they did in the last iteration.
Regardless of however much you see fps improvements in 2024, the main thing is that Asobo’s claim that aircraft would be more complex but somehow smoother seems valid. I’m having a hard time believing the lack of a cabin in 2020 is the sole (or even primary) reason.
I’m still not convinced streaming content is the best approach but it looks like sim stability and performance will further improve between now and the height of summer. For me, 2024 is now very usable, compared to how it was at launch.
FS 2024 SU Beta as recommanded by ini, I made 2 flights, I had contrails on both.
I notice the elevator trim is out of takeoff config at launch. One click brings it into green.
Anyone on MSFS2020 still getting a loud bang on takeoff rotation after the latest update?
I use FS2020 and the only thing I noticed is that before the update, during rotation I only had to pull the Joystick slightly, now it seems like it almost goes up on its own.
