Lower GPU usage before landing

Hello, everyone. I have noticed that my gpu usage drops from 95% with absolutely smooth to 75-80% shortly before landing and I stutter and get a drop in fps due to the main thread limitation. everything is fine at take off. Flight time less than an hour with the FBW (developer version), but also with other aircraft, RC is on, 400 Mbit lan, i 9 12900K, 3080 ti, 64 GB RAM, live traffic on, no PT, driver 511.23, FPS block with nvcp, all other drivers up to date. LOD with FBW 150, with GA on 220. maybe someone has the same problem or even a solution.

I do have the same problem, same system as yours… my GPU-usage starts at 100% and after a while it drops down until 60-70% and FPS go down from about 60 to around 30 and i absolutely got no idea why. It’s very annoying having such a good CPU and GPU which is utilized 60% only

OK. do you have an idea what that could be? i tested a lot. with and without community folder etc. I don’t have this phenomenon as much if I fly over water for a long time before landing …
