Frames drop to 10 a few minutes after launch

asked Oct 9 by rich142 (48 points)

When I usually start a flight, I'll get around 20-25 fps. All of sudden, the fps will drop down to around 10. This happens at random times, sometimes during takeoff, during cruise, or during landing. After a few minutes, say 4 or 5 minutes, the frame rate jumps back to 25 and will remain there for some time before falling back down to 10. My pc is no top line rig, but the CPU is at a steady 30-40 % during the entire filght and not much load on the GPU (~20%). Most of my setting were on medium and I have the threaded optimization fix applied. I even turned down all setting to zero. X-Plane looks really bad now, but no improvement in performance.

Happens with all aircraft and airports that I have tried to fly to/from. Using the default Cessna, 747 and Zibo 737 all have this issue. I never had this issue during the demo version, which was 11.02

i came across people posting similar problems on the .org forums and , but there was no solution anywhere. Hope someone here can help me out .

Thanks in advance

I would recommend trying the X-Plane 11.10 update once available to see if it has helped any of these issues. It should be available soon.
