Why is rendering suddenly ugly when playing/simulating?

Hi, I am having the same issue. But the solution would not make any difference for me :(. All Engine scalability settings are at 100% and “Epic”

Additionally I am having this shaky camera for some seconds until a better quality kicks in.

It looks like the engine is very busy building up the environment, therefor lowering the quality. But that’s only a wild guess.I recently switched to 4.13
