Huh, it’s not happening to me as well now. It might have been due to something else, in conjunction with rapidly changing time. I do remember I was playing with Ultra settings when that was happening to take some screenshots. Maybe it’s the texture related settings? I have a LOT more stuttering with texture quality at ultra, possible due to having only 6 GB of VRAM. Maybe it’s getting overloaded somehow.
Edit: It happened after a flying a bit further, ignore what I said above
Hello all,
I had performance issues as well (see my postings) but when I went for a flight yesterday night it was alright “all of a sudden”. I got more fps and smoother overall performance in the menu (from 40 to 70) as well as the sim (from around 10-20 to 40). It doesn’t say “limited by main thread” anymore and says the gpu is now the bottleneck (which is fully utilised).
I did some tweaking but only minor stuff iirc while keeping graphics settings high or even pushing some of them to ultra or higher values (detail sliders now at 130). I kept the native resolution and that one slider at 100 all the time. Don’t really know where that boost in performance is coming from…
I watched a video on youtube where this dude turned of all those useless options on the Windows Gaming page, like game mode and screen/audio capture or whatever. Give it a try. Disabling antivirus doesn’t change a thing for me, neither does flying in offline mode (and I have really bad internet 4,5 Mbit/s). I believe I haven’t touched the program settings on the nvidia control panel after installing the latest game ready driver apart from making max performance a priority.
I’m only flying around my local area in the C172 G1000 but I can now do so at 35 fps minimum, sometimes reaching 45 in the cockpit. i can live with that. maybe i’ll be able to recreate the performance issues to find out what the actual culprit was.
Okay. Can you test the scenario I described in my other post? I’m curious to see if you can reproduce the issue.
I was wrong, it happened. I flew a bit further and now I’m stuck at ~20 fps with stuttering, and 40-50 ms frametimes. Looks like texture quality doesn’t matter.
Exactly my situation.
Unfortunately I think we, who suffer are probably like 5% of the user base, so they don’t care that much. We see only our own perspective. I think if performance is not within top 10 issues then the problem concerns relatively small amount of users. They will either address it much later or…never forcing us to upgrade our hardware, especially CPU
This is a known issue (it was posted on reddit), and the way you fix it is by doing this:
Do this only after the game has reached the main menu:
Download Process Lasso, right click FlightSimulator.exe in the process list, go to Priority Class > Current and disable “Windows dynamic thread priority boosts enabled (*)”
It should look like this:
This should make the performance as good as when you click off the game’s screen.
OMG same CPU! What RAM do you have? I’ve got DDR3 1600 CL7. What LOD value are you using? Can you post your config like a screenshot or something? In my case none of the tweaks gives noticable improvement. Maybe reducing LOD to 30-40 does a bit, but it still stutters.
I see the same thing when changing day to night or back mid flight. Everything changes fine but then there is a 5 to 10 second pause. Long enough that I want to reboot but every time I wait it comes back. In my case though, everything is normal after that. No major reduction in frames other than what night time tends to be anyway. 2 to 3 frames lower at night in a city.
None of the settings was getting rid of the stutter. I use 100 lod, but 150 is also no prob. Did you install the 2004 update?
I have an i5-7400 series quad core, 24g ram, MSI RTX 2060 super 8g, 1T Samsung SSD and 25mbps internet connection. Most of my settings are on medium… with the exception of clouds, reflections, and a few others… they are on high. When I first get into the planes… it is a bit choppy and stuttering and freezing… but I give it a minute… and then it’s buttery smooth. I also am using live weather. I turned off live traffic… although it wasn’t too bad, but I could see some stuttering. Obviously I don’t have nothing near to the high-end systems I’m seeing on here that are having issues… so I’m not sure why some are having more issues then others. I hope everyone can enjoy this soon… because when it is working… it’s a real joy!!
I get the pause too if I change time or weather for any reason. But then it goes back to buttery smooth again
Hi so even when turning or panning there are no stutters? I have a i5-7500 and I’m able to maintain 30FPS, 30HZ but still get stutters particularly when turning and panning?
Same stuttering issues here, “focus” to another application fixes it for me - now I leave “calculator” running and alt tab to it during play and drag it into the corner so the game continues to run normal. It’s nice in a way, I was able to move all my settings back up to high as lowering settings had nothing to do with the stuttering. I just submitted a ticket…
There is a tiny, tiny bit of stutter every now and then… but the longer it runs… I’d say like 5 minutes… it won’t stutter for me at all… as long as I don’t change time or weather. I also make it a point to circle around my cockpit 360 degrees… which for some reason helps
That focus issue can be fixed by doing this: Dreadful performance - #640 by TessellatedGuy
Seems like flight simulator doesn’t play well with how Windows automatically boosts thread priorities when the game is in “focus”. It’s probably boosting the wrong threads and causing performance issues instead. Disabling thread priority boosting makes it so windows doesn’t touch anything, so the game runs as if the game isn’t “focused”, even if you are focused on it.
Edit: Remember to only do that after the game has loaded into the main menu, otherwise it caused massive freezing for me.
Yup, going try that as opposed the alt tabbing… thanks for posting!
If u have Ryzen 5 3600 then the cpu is good enough.
Hi guys,
Does anybody have an issue using the external camera and moving the mouse around, which causes a stutter at certain angles? I don’t have any stutters inside the cockpit, only when using the external view- 2600x Rx590 1440p 25-30 FPS.
Ryzen users need to look at their RAM speeds also. I was only running at 2400mhz until yesterday. Threw a couple of 3200 sticks in and my fps seems to have improved by about 50% to playable levels. Just. Caching is still slowing me down in populated areas but improves itself after a minute or so.
I am still getting horrible stuttering when flying through clouds.
