Hello sim pilots

Here is what happened to me after ~ 2 hours flight, in reason I chose to fly across the north pole (no terrain at all) just to test how msfs su9 works after mid stress the CPU and GPU, so I started the flight with 146 professional, and the FPS was around 50 to 60 then the FPS begins to decrease.

after 2 hours reached approximately 28 FPS(GPU temp under 70) (CPU temp under 60)

 after a while, FPS drop to 22 (GPU temp under 70) (CPU temp under 60). NO terrains should be not a lot of stress

then FPS 11 (GPU temp under 70) (CPU temp under 60)

then to 9 and 8 FPS 

While I press ESC and go to the menu, FPS increases immediately to 99 FPS 

This is my MSFS settings

Hope you got solution.

I tried it with overclocking and default settings nothings change.

Theres loads of topics on this issue on this forum. Microsoft has issued a statement after su9 saying they are investigating the problem. But dropping fps over the flight has been a problem for many months for some people. 

Fingers crossed they fix it

Thank you Steve 🌹

Check the images in control panel - printers to make sure one of the dx button lights on a controller (yoke, throttle) is not flickering. I had same problem a year ago. I had assigned lights toggle and the lights were going on and off so rapid it was eating up fps, which dropped little by little and by about 45 minutes was down to single digits.It was flickering so fast on and off that I thought it was on steady, but it wasn't. I deleted the assignment and no more problems since then for months now.

I doubt this is your problem but it was mine. Something is slowly robbing the cpu of its ability to perform. Could be lots of things. The MSFS forum has long threads on this.

One specific variety of the FPS drop after long flights is related to traffic. A couple of months ago many users could fix their FPS issues by just turning the traffic off and back on again during flight. Not sure though if this still happens with SU9, but at least it's worth a try.

dear Fielder

i open the printer file then what to do ? where can i see if its flickering or not? and how to delete the assignment?

you mean here ?

ill try it right now

I had this problem on a long flight in the DC6, 5hrs in the stutters started, as they got worse I saved the flight reloaded it and all was back to normal, yes a pain in the backside, but it only took  a couple minutes and better than enduring the stutters.

I do many flights lasting two to three hours with no problems at all.

Might also be worth looking into older threads about this issue - I haven't really experienced it myself, as I've been flying shorter legs lately (1.5 hours max). That's why I'm not entirely sure about the exact procedure the affected users followed, better search for what they wrote.

You can also try to switch bing data off and then on again - it worked in my case in the past.

How?

You have to look at my DC-6 post here DC-6B

Yes, that was what I was talking abut. If your controller had DX buttons they would show up in your bottom diagram along with the 3 hats diagrams. And when you press a button the light turns on. A flickering is when it turns on and then off and then on and then off, cycling like that rapidly, faster than you can hardly see. This eats up CPU, tires the CPU down over time, heats up the CPU and a half hour later fps are way down. An hour and they are single digits.

The flickering means you assigned a toggle command and the button has been pressed but is not releasing. so the command just toggles on and off rapidly forever.
