After playing a few hours, FPS drops from 40 to 5FPS

Put this in another thread but happening to me again.

Massive FPS drop because of SU9

Happen to me again. 4.5hours flight time. FBW NEO Development version. o/c i5 9600k @ 4.8 32GB DDR4 3070 running latest drivers. Nice and smooth at the start. Then down to single digit FPS. I checked my processes and my GPU is basically just idiling so it might have something to do with the GPU? [processes] [ybbn4] [ybbn5]
