Loss in performance whenever rolling cache seems to be full [2024]

ISSUE DESCRIPTION

Description of the issue:

After setting up the sim I set rolling cache to a custom location and upped it to 64GB. After several flights which went just fine out of the sudden my performance dropped drastically especially on ground level (~10 FPS less on my mediocre system). Sound also started crackling on moving the camera around
I decided to delete the ROLLINGCACHE.CCC manually to see if the issue which persisted after restarting the sim will be gone right after which in fact was the case. I now left the file size at the initial 16GB to test it more.
After some time the performance started to be quite bad again, so I deleted the file yet another time with the same result and did that yet again right now which is why I file this report :wink:

[PC Only] Did you remove all your community mods/add-ons? If yes, are you still experiencing the issue?

Only a pretty limited selection is installed which was not removed.

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)?

After quite some time depending on amount of data which was streamed.

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

Precondition: set a custom rolling cache location like C:\MSFS\Rolling Cache which is similar to mine. Also use the high to ultra graphics preset so the cache won’t take too long to get filled.

  1. Perform some flights in some areas with loads of PG, at best at low level. Monitor performance each time
  2. Restart the simulator now and then in between flights - at some spot performance may drop
  3. Delete the ROLLINGCACHE.CCC file so a fresh one will be created
  4. Do another flight and compare performance to the flights before removal
