The Issue
Whenever I fly (or just sit on the ground), FPS decreases gradually over time, making long hauls and long flights impossible.
Emphasis on Time: I sat on the runway for 5h straight and had the FPS drop.
This issue happens with the B787 and the A320 at least, haven’t tested on GA Aircraft.
The only way to fully recover the FPS is by restarting the sim.
I tried :
-Disabling the ATC window
-Disabling the VFR Map
-Looking away from the instruments for a couple of minutes
-Using ISLC v1.0.2.2
-Disabling fullscreen optimisations
-Enabling/Disabling GPU Scheduling
-Enabling/Disabling Gamemode
-FXAA/MFAA are off in the NVidia Control Panel
-Excluding FlightSimulator.exe in the windows defender scan settings
Nothing has worked.
This is just after starting the flight, 30FPS:
This is 5h later…20FPS:
Now interestingly, sometimes when I pop into the menu and back in the game again, it freezes and I have some FPS recovery, sometimes 100% of FPS back, sometimes just a certain percentage back. This happens also when I go into windowed mode and back into fullscreen. Sometimes, the recovery doesn’t happen at all…
GPU usage goes down, but I don’t know if it is because of the CPU or not. I don’t know if it is memory, it is not full, pagefile is large enough and hard faults are rare and when they do happen it is 2/3 hard faults per second.
Interestingly, when going back in the menu, GPU usage goes back to 100% or near 100% like at the beginning off the flight:
This is after a freeze after going back to the game from the menu, something changed in memory and there is a small FPS recovery:
And these are my CPU temps, showing it is not thermal throttling:
