MSFS 2020 and stutters

Dear Devs, I am well aware that modeling the whole world with stunning detail, is a HUGE undertaking, and this has been achieved for the most part admirably. My warmest congratulations.

Though, among other things, the main goal has not been achieved, a fluid flying experience.
Even with my high-end rig (specs below) and even cranking down the settings to the lowest levels, MSFS stutters. Even at lowest settings, and no traffic, it is not capable to hold and maintain SOLID, FIXED 60 FPS, which syncing to the 60 HZ of my monitor, are the ONLY WAY to achieve a stutter-free-fluid flight. Moreover, even at its lowest settings, MSFS it is not even capable to hold and maintain a minimum of FIXED, SOLID 30 FPS, that would at least be BARELY acceptable. With V-Sync enabled and limiting to 30 FPS, MSFS goes down to 18-22 instead to FIXED, SOLID 30 FPS, which my rig would be perfectly capable to hold, proof being that limiting to 60 FPS, it achieves up to 40-50 even with much higher settings.

I am asserting all this, because with the same rig, at the very same locations, (Las Vegas, Batumi, Dubai), with the very same clear skies, and the very same time of the day, month and year, I can achieve those SOLID, FIXED 60 FPS in another flight simulator, (albeit a combat one), with the highest settings, no matter the twists, turns or situations. Granted, with a far lesser realistic quality of the terrain, but with an equal or even superior quality of the external and internal graphics and features of the airplanes themselves and their shadows / lightning. And btw. I achieve those SOLID, FIXED 60 FPS also with several photorealistic games….

I have spent the best part of the last three weeks watching videos on Youtube, reading this forum, googling, etc. and applying dozens of tweaks, both internally and externally to MSFS, including experimenting with different sizes and quality of rolling and manual cache, (btw. 200 M/bit cabled Internet connection) in order to find a solution to this issue. I have NOTHING in the community folder. All has been to no avail. My conclusion is that MSFS, in its current state, cannot be considered a proper flight simulator, but more a game with stuttering stunning worldwide graphics…

In addition to that, inexplicably, functions which were present in FSX 14 years ago, have not been implemented, like a fly-by camera, tower camera, replay, and don’t get me started on that ridiculous way to “hide” the navaids….

i7 6700 K/ 1070 ti / 32Gb / SSD Drives and I average in the low 30’s and am quite happy to achieve that.

Based on the feedback of much higher spec machines I don’t see any point to upgrade for some time.

Must be a bit frustrating with all that horsepower though, flightsims are always like this at launch.

Yep. I spent around ÂŁ3000.00 upgrading my system specifically to run MSFS. i9900ks running & 5.1 all cores stable, low temps (water cooled), RTX 3090, NVME drive, DDR4 32mb 3200 memory XMP II etc.
It runs ok, I do get steady 40’s-50’s, FPS, happy to turn settings down a bit, but it micro stutters particularly when turning on the ground at an airport. And dont get me started on the forced updates that break everything each time leaving things worse than they were!

Indeed… Tell me about upgrading my system specifically to run MSFS…

Without any disrespect and obviously without knowing how well configured your system could be:

It has somehow become the norm that people will throw a spec into this forum and then start complaining that their system is not performing well.

It should be understood that a spec is nothing more than just a spec. We don’t know what your system configuration is, what other applications might be running, what “optimisations” people think they have implemented because someone said so on Youtube.

I am running on a 5 year old system (i7-4790K, GF 980Ti) and I am getting stable 32fps and NEVER had stutters even in the most heavy scenery, with most of my settings at HIGH.

But to get there, I optimised my system

  • airflow and cooling
  • quality power supply
  • BIOS settings and intel cpu energy management
  • slim drivers installations
  • ZERO other apps on the system, even uninstalled the browser
  • no peripherals apart from the controllers
    And so on.

I am also not broadcasting on Twitch, not recording a video of my screen, not running a replay mod, not running navmaps on the same computer etc.etc…

Well, also without any disrespect, If my system wold be badly configured, I would not achieve those
SOLID, FIXED 60 FPS in a half a dozen of other photorealistic games and the “other” flight simulator.
The problem must lie within MSFS 2020 itself. …

Honestly with my system I’m getting 40 - 60 FPS steady at 1440p Ultrawide in a mix of Ultra/High End settings. No issues/crashes at all. Since the last patch I can’t crash the game no matter what I do it’s beautiful.

I found the biggest issue causing my shudders and crashes was AMD Freesync as I have multiple monitors, I turned it off on both displays manually and in the software and Auto Undervolted my GPU with the AMD software. Game is running better then ever. Maybe the Nvidea G-Sync is causing similar issues? Worth a shot.

My System:

  • Ryzen 3700X
  • MSI Radeon 5700XT Gaming X
  • MSI B450 Carbon Gaming
  • Corsair 32GB RAM @ 3600mhz
  • NVME 1tb WD Black
  • Display 1 - MSI 34" Curved 1440P Ultrawide
  • Display 2 - MSI 24" Curved 1080P

Well, I don’t have Nvidia G-Sync… Otherwise I would have mentioned as I started the topic.

Someone needs to develop an App/Diagnostic tool for MSFS that allows us to fully understand what is causing the performance issues while running MSFS.

Remember that MSFS is the new Crysis and is pushing your system to places no other game has pushed it… While the game is well-optimized, current-gen CPUs can’t give 4K60 on high or ultra.

Well, that’s why I wrote that not even at low settings it runs properly…

I would seriously look into those issues. If I switch to low, I am getting 80fps at UW 1440p.
What’s your render scaling?

Why don’t you check this post and do everything as stated for a try.

Super strange, might be an issue with your hardware when under a heavy load. Power supply issue maybe? I know you said it runs good in other games but there isn’t really another game that puts the same kind of load on your machine.

I can also get that @ 4K. I did not make myself clear…
Maintain SOLID, FIXED 60 FPS, and so syncing to the 60 HZ of the monitor,
is the ONLY WAY to achieve a stutter-free-fluid flight / movement.
That is EXACTLY what I achieve in a half a dozen of other photorealistic games and the “other”
flight simulator.

It is impossible for the Dev team write software for all hardware types, mixtures, and different edge cases. It’s simply not possible. I code webapps and all I have to contend with are browser types and I get enough issues with supporting those. Sometimes there are combinations of systems, hardware, and software that just don’t like each other.

What they can do is continue to optimise, read feedback and get usage stats to further improve the sim.

From the ground up MSFS is truly ground breaking and I personally feel they are doing really well.

I run the sim on a 1yr old laptop with an i7, 20gb ram and a 4gb graphics card. I’m getting 19-22fps on medium low settings.

CaptMatto, Well, that’s were my efforts ideally pretend…

They are; from the live streams, to the developer blogs, it’s coming but it will not be immediate - no software is ever finished and is never at a point the developer is happy.

I have to stop myself refactoring code I’ve already written because I’ve found a better way or learnt a new skill. If I did that I’d never release anything! :slight_smile:

I suggest having a good hard look at your settings. With your system you should NOT be having the issues you are describing. I would start by ensuring everything is running at stock levels. No overclocking or V adjustments. NVidia controls default and Experience disabled.
Get a base line from there and then start trying some of the adjustments, here…

I have a pretty middle of the road system and am only running 1080p, BUT I have most MSFS settings on Ultra or High and generally humming along at 45-50 fps with no stutters. Just for a test I tried 1440 on a small monitor and still managed 30-35 smooth.
There are obviously some issues that Asobo could improve on with the optimization but in general the sim runs pretty well since the last update (aircraft issues aside).

  • B360 MB
  • Corsair 32GB 2666
  • i5-8400
  • RTX 2060
  • 1000w Corsair PSU

FYI, do not even dream of 60fps locked at 4K Ultra. It ain’t gonna happen without alien technology.

I am very sorry to say this, but your “rig” is not even near powerful enough to make this sim run at SOLID, FIXED 60 FPS all the time, like you are yelling it should.
It could be, if you are standing still in the middle of the desert with no weather and going offline. That’s a fact!

C44MO, well is your rig more powerful than mine? It scores better than 90% of the results in 3DMark
Port royal, and That’s a fact!..
