I haven’t played fs2020 for 2-3 months. Last time I played Asobo had made some big performance gains and I was getting around 45 fps at my local airport flying the default 152. I’m about 10-15 fps short of that now. Struggling to reach 30 fps now and often around 25 in built up areas or lots of weather. Just interested to know if generally recently the sim is running slower due to all the updates, esp the 25 anniversary edition?

Hello,
Welcome back!
Tech Talk is the place to discuss performance. I have moved your topic.
Thanks but where is Tech Talk?
It’s one of the blue categories:
Please post specification. Difficult to help otherwise.
I know it’s been great hasn’t it, especially with the latest Nvidia 536.40 drivers 
. Great performance from this sim and to think it will only get better with MSFS 2024.

Thanks by my spec hasn’t changed so not really relevant. Just interested to know what might have changed in the sim recently to bring fps down so much and if others have experienced the same?
Guessing that’s sarcasm, my fps is 10-15 worse not better!
Appreciate that your spec hasn’t changed. However most people are not having the same issue as you are having and have found performance has improved. So many things can affect performance, from driver versions, sim updates, bios configurations, location in the sim, aircraft type, PC architecture, CPU maker, GPU make etc etc.
A lot of the time its a case of eliminating the obvious, and that starts by understanding the spec. Then you can work back to an area where you can identify the issue.
It was a bit cheeky perhaps 
, but I’ve genuinely not had any performance degredation. I understand with the AAU2 update some folks are reporting some fps drops with planes which make heavy use of glass cockpits, but that’s probably due to an increased simulation load, something MSFS 2024 threading can hopefully address. In the meantime you could try turning down traffic to compensate.
I’ve include the reasons why I’ve not seen performance degradation. These results are from two older PCs and are consistent with past performances. My main PC is a 13900K RTX 4090 and quite frankly if I posted these results it wouldn’t at all be fair, so I’ve just posted 2 ‘normal PC specs’ for comparison.
These settings below are MSFS defaults @ London City a highly built-up area in the sim with the same plane you have a Cessna 152. I usually fly GA planes and small executive jets. In-game settings use Live Players, Live Traffic, Live settings.
The two PCs for comparison, a mid-range and low-range PC. As you can see both systems offer excellent performance in the simulator which shows how well the simulator scales. I could optimize the low-end PC a lot further but I’m happy with the general performance and visual look on this PC.
PC 1 - Mid-range - Windows 10 - i7-13700K GTX 3070 Ti - MSFS TAA, HIGH-END 1080p - 100+ FPS
PC 2 - Low-range - Windows 10 - i7-4790 GTX 1070 - MSFS TAA, MEDIUM 1080p - 45+ FPS
Both PC’s are using the Nvidia 536.23 drivers and achieve comfortable better FPS than what you are quoting so as @zooze74 has stated, perhaps it would actually be better if you gave us your specification so we can look at why you are getting poor FPS.
Sometimes graphics behaviour can change and you may need to tweak the graphical settings to get back the same performance or perhaps you added some system software which is chewing up CPU cycles, it’s impossible to know for sure, but it’s too easy to blame the sim for bad performance.

Thanks for your post very helpful - yes somehting has clearly happened while Ive been away. PC specs are
Processor Intel(R) Core™ i3-7100U CPU @ 2.40GHz 2.40 GHz (no overclocking)
Installed RAM 4.00 GB
System type Windows 10 64-bit operating system, x64-based processor
Graphics GTX 1070 (latest driver)
Ah I see, so you are using a laptop? I think your specifications falls below the minimum specifications for Microsoft Flight Simulator.
This has the minimum specification for MSFS for an Nvidia based system using a CPU with an Intel i5-4460 which is 43% faster than your CPU an Intel i3-7100U. Further more Microsoft recommends using 8GB of RAM as a minimum instead of 4GB.
One thing you could try is lowering the resolution to see if that helps, maintaining aspect ration, so if your laptop is a 1080p (1920x1080) screen trying lowering it to 720p (1280x720) and see if that helps?
Ah I’m an idiot took these off laptop! No i have sim installed on desktop - here are specs
Device name DESKTOP-LRPEA8P
Processor Intel(R) Core™ i7-7700 CPU @ 3.60GHz 3.60 GHz
Installed RAM 32.0 GB
Device ID CB880A39-12AF-496E-BA78-43944F23361F
Product ID 00325-96032-89125-AAOEM
System type 64-bit operating system, x64-based processor
Graphics GTX 1070
Pen and touch No pen or touch input is available for this display
Just as a note: UserBenchmark is heavily biased on Intel’s side and is so unreliable that it’s considered as a joke in the tech space. Its unfortunate since its an easy platform to use, but makes it an untrustworthy platform for those looking at fair comparisons.

Thank you for the advice @FlyingCookie650 Questionable metrics against user submissions aside, I think it’s ok to prove that the posters system is below MSFS minimum specification which was the intended purpose here, that’s all.
Ah right, so to be honest, that looks like a very similar specification to my ‘low-range’ PC I posted i7-4790 CPU @ 3.60GHz so you should not really be getting the sort of performance degradation you have described with a 12 fps drop from 45 fps originally, not consistently anyway.
I think with that system you should achieve 45 fps in a Cessna 152 almost anywhere as long as you stick to what I would call reasonable settings like MEDIUM graphics.
Feel free to post any scenarios and graphics config and I can try my system for comparison.
Thanks. It’s strange as I was getting around 45 on high settings with this rig with default Cessna 152 but as you say could be 101 things. Will post settings
