FPS gets lower and lower

happy load in flight and start up FPS is 60
then takeoff FPS is 55
then cruise FPS is 60
then approch FPS gets lower about 50
then final to touch downFPS gets lower then lower until 35
then taxi to the ramp the FPS come to 40

what about the WT G1000?
what about DA62X?
what about my PC and setting ? (9900K+1080ti+32G+2K display)*medium->low end

no Navigraph
no other addon just from NZAP-NZCH
about 2 Hours flight

This reminds me of the old FSX,A frustrating experience.

MSFS still has a long way to go, hope it gets better and better.

If you’re using AI aircraft, this could be the root cause.

I have discovered this too but then I discovered changes related to MSFS within the settings of the new Nvidia 457.30 GPU driver. I went with the new changes/recommendations that appeared within the new driver settings and turned off my GPU related graphics settings within the simulator and restored my performance. Just so I don’t have to explain this all again, here is a link to my findings with this new driver…

Are you sure this is the same issue? Surely the driver will affect the game systemically, so you get a consistent loss of FPS when you change the settings.

What is described here could be related to the AI aircraft issue we’ve discussed elsewhere, or could be just a normal experience when you have dense scenery and models. There’s a lot of threads related to large airports causing framerates of 10-15 FPS even with high end systems (Paris Charles de Gaulle is one example).

What’s worng with 50fps? Sometimes I have little less than 20fps and all is ok. It starts to produce problems when you come permanently under 15fps :point_up:t3: :man_shrugging:t2:

I am not sure about anything, there are so many changes being made to the simulator, drivers, payware and freeware add-on’, it’s difficult to keep up. I have no AI aircraft enabled, I have certainly smoothed out my simulator performance with the new driver, even when the frame rates drop to 25 using the A320X.

@TheAviator3506 the question is are you seeing a gradual slowdown in FPS over the course of a flight, or are you talking about a general slowdown based around your experience with the driver? If it is the latter, then we’re off-context.

On other threads we’ve done exhaustive analysis of a slowdown caused by AI aircraft. They don’t get destroyed when they are out of range, so they gradually bog down the performance of the sim. When I see discussions exhibiting these symptoms I want to see if the user is affected by the same bug.

What is the problem? Your fps is very good for a mid-range PC. I’m getting 25-40fps on ultra with a similar setup on 3440x1440. If you want it to run on 60fps then it won’t happen no matter the hardware. At least not for now. Stutters are gone which is more important.
Fps will change depending on where you are, what’s the weather, how many ground vehicles are around, how many buildings&trees, water, ai/multiplayer aircraft. It should fluctuate quite drastically.

My experience was an instantaneous slow down with lows of just 5 FPS in places, something I had never experienced before. Charles

5 FPS. I have seen my laptop come down to 10.0000000 FPS

It never gets below 10.0000000 which makes me think there is some sort of lower limit in place, that causes the system to preserve the 10.00000 FPS, at the expense of other processes.

My frame rates were not very good either, I am running in windowed mode and 3 screens not stretched all the way over gets to distorted and bad fps until i discovered that turning down the Render Scaling to 60 or 70 Bumped my FPS right up and no stutters.

Someone can correct me if you think I’m wrong but in my mind, the lower you are in altitude the more detail you will see. Also, the lower you are in altitude, the faster the world around you moves. Both of those points would hit performance. Last, if you land at a hand crafted airport, this will also hit performance a bit. I would absolutely expect lower FPS’s in these cases.

Had this same issue after the update. I made 2 changes and I have not yet gone back to see which one fixed it for me. I have an Nvidia 2080ti. 1) Changed the path for the rolling cache from my local C: drive to my NVME drive. 2) In Nvidia control panel under Configure Surround, Physx I set the PhysX processor from Auto Select to my 2080ti. After that my FPS was back to normal.

I suspect it may have been the Rolling Cache setting. The update changed the path to my boot drive. Can’t have that.

thanks will try that because playing first time after update and what I notice is that graphics is not nicer at all, could be worse (trees) yet fps dropped massively and it stutters out of suddent it never did…

Edit: changed the PhysX settings for my graphic card instead of auto and it’s fixed, stable 45-50 fps like before.

You’re very much right. In a large city, at 1200 AGL I get around 35 FPS. Going up to 1500 AGL I jump up to 40 FPS. Anything over that I max out at 45 FPS. Mostly high settings with a few on ultra.

This sounds about right to me. At your departure the world around you is able to be loaded while you are sitting on the loading screen, as you fly to your destination you are going to be loading new textures. Then when coming into your destination, especially if it is a photogrammetry area, you will be loading tons of new textures that did not have the ability to be pre-loaded while you were waiting on the flight to load at the beginning.

Sure… and before I had no issue and constant frame rates… it was kind of magic then?

Hey… some things I have experienced with this sim sure does seem like some kind of external forces… or magical substance could have been at play. After nearly every patch performance would be different. Heck seems like on a daily basis performance changes day to day. Sometimes I can hit 45FPS in a heavy thunderstorm then next flight could be sunny and no clouds and struggle to hit 30FPS. Plus every system seems like it can have completely different results. Honestly its just impossible to say what is going on most of the time.

Why do I feel more confused the more I look?

Check the solution that saguarian came up with, have no idea why, because the solution for stutters in last patch was to set it on auto. Now it seems that setting it from auto to your graphic card in nvidia settings fixes it… I know. I’m just as confused and iritated. But from 30 falling to 18 fps when doing turns… it’s now stable 45-50 fps after changing that : )
