Btw. When transiting back from 2FPS to normal, I can see this immediate GPU and NETWORK load increase, whether CPU and MEMORY load remain at the same level, unchanged. Therefore I think that the root cause is somewhere at the thread management level, because before this transition, theads are like crazy switching. When switching from 2PFS to normal, threads are loaded in rather stable way and spikes on threads disappeared. What I’ve found very interesting is, that overall CPU load remains at the same level about 20% in my case:
