MSFS suddenly unflyable

[Soulflight 97]

Hello everyone,

i dont know if something happened to my system, or to MSFS, but from 2 days ago to today the FPS i am getting became completely unflyable. It is noticeable in map view even, when i try to take off from anywhere it becomes a slideshow. FPS around 1 or less. It seems like the sim moves for one second and then hangs for another second. I already disabled all addons of testing but the issue is still there, even on vanilla MSFS.

System is not the best but ran smoothly until today: Ryzen 5600X, GTX 970 4GB, 32 Gigs of RAM, Windows 10. All at stock speeds.

When I get stutters I delete the rolling cache... maybe give that a try

did you update to the latest nvidia driver , think its causing me some issues

Your videocard needs upgrading as this is what is holding you back a great deal from a hardware perspective.

I would suggest that your first step should be to update all of your drivers and revert to default nvidia and msfs settings, then work your way up from there

Well this one i know, but if i had like 1000$ to spare there are different priorities in life. 😉 the gainward phantom 970 I have isnt tat bad in performance, the major setback is only 3,6 Gig usable VRAM, which is why I run MSFS on medium texture quality and I am usually at about 30 FPS with this.

No, i think i did so like 3 months ago.

I might also be looking on a RAM issue here, as I just noticed that when running a prime95 large FFT test, my machine also starts microfreezing every 2 seconds.

mem test in windows or there are other memory test software online

Solved. I deleted and rebuilt the rolling cache. works normal now. thx everyone.

I have never used rolling cache, never needed it, no problems whatosever.

It happened to me randomly as well. Turn off "on-line traffic" and it should take care if it. Hopefully MSFS will fix it next patch

Hi,

How do you delete the rolling cache? Thanks.

To do this, follow the steps below:

Open the simulator and click the "Options" tab in the top menu and click "General"

Click "Data" from the left sidebar.

Scroll down to "Rolling Cache Settings" and click "Delete" next to "Delete rolling cache file.

simple  search on  google  came  up with this option  🙂

After you delete it never turn it on again, you will thank me later.

My experience of the "rolling cache" is everything works fine for a while and then at some point during a flight one day things start acting very odd indeed. A sort of stutter starts to occur but it's unlike any stutter I have ever seen. It will get worse and worse until it becomes ridiculous. Like a stop-motion video but it's going back in time every few frames. However, if you look at the FPS counter it reads normal.

The first time it happened to me it felt as though the sim was trying to render two worlds and shortly after getting that impression I looked out of the window and saw the buildings and trees were occasionally disappearing and phasing back in. Sometimes doubled up with the second lot in a slightly different position. It was like a glitch in the matrix.

It took me about 15 mins of watching this get worse before I wondered if the rolling cache was to blame and so I went and deleted it in the flight and immediately it was fixed.

However, I had it happen two more times after that and each of those times deleting it during the flight didn't stop it from happening. It only went away after I deleted it and restarted the sim.

Because of this ability to ruin a flight I have now disabled it and fly without it.

I have no real idea why this happens but my theory is that it works fine until it reaches its capacity and then starts causing problems. It is just my theory though.

My advice is that unless you never leave a certain area during your flying then turn it off.

Yes, that exactly was my experience now. Now i wonder what the RC is doing anyways? It seems to have some sort of "storage leak" at some systems where it gets full and is never cleaned by the system ever again. Is the RC only saving network data and thats it?

I believe it is storing all the area data you are flying over so that when you fly over it again it does not have to pull the data from the server. So if you only fly around the same place it's actually very useful. However, if you are flying around the world it's pretty pointless.

I'm not sure what it's doing when it gets full though. The term "rolling" suggests to me that it should dump the earlier data in favour of the new area you are flying over but I'm not convinced it does. I think it fills up and then acts up.
