Hi all! There was such a situation in my project. The main character stands still, I turn the camera at a certain angle and the fps starts to drop, then it recovers, through profiling I realized that the problem is in FPBDRigidsEvolutionGBF::ComputeIntermediateSpatialAcceleration
Disabled clothing physics simulation, FPS drop remained
UPDATED:
There is no fps drop:
