Why is rendering suddenly ugly when playing/simulating?

I have this weird rendering issue. I’m not sure when this started happening, but now if I press play in my project, it seems to start rendering with very low resulotion or something like that. Here are screenshots comparing how it looks when editing vs when pressing play (or simulate).

The rendering is set to high quality desktop, but no matter what I change in the rendering settings, it remains ugly. Any idea what causes this?

In the toolbar click settings → Engine scalability → Resolution scale. Put it to 100% to get full resolution while playing. It was probably lowered automatically because of low fps.

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
