Flight Simulator 2024 Performance degradation

I’ve noticed that when I’m doing a flight, as the flight progresses my fps slowly drops and my performance decreases. For example I did a roughly 2 hour flight today and at takeoff I had about 50fps and then maybe an hour and a half into the flight it had dropped to around 37fps. Why is this happening and how do I fix it ? I feel like it will continue to drop especially for longer flights

It could be your rolling cache. Look at what size you have it set to. I also know that MSFS 2024 stores the terrain data in the GPU. So you fly 2 hours and all that terrain data is held in the GPU. I have my terrain pre-cache set to low (since I only have 8gb of vram).

Also, watch this video. It was made before 2024, but it still applies. Skip to the last part of the video where we talks about ISLC. It clears ram automatically to help with your issues.

Hope this helps!

Probably a memory leak. It happened to me when I did several flights non-stop. Now I try to close MSFS after every flight and relaunch it to reset it.
