After installing UE 4.10.1 - poor image quality

I installed the new 4.10.1. version and now everything is very dark and of very poor quality - no antialiasing. In version 4.10. everything was OK and camera adapted to different ligthning conditions. I checked/unchecked auto exposure in the project settings, but there is no difference.

I opened the project that I bought from Marketplace (HALAchiViz) and it looks much darker and of poor quality now, too.
There is a message “Texture streaming pool over 297.36 MB”. What does it mean? (Screenshot.jpg)

Does anybody else have this issue? I am a beginner and I really don`t know what to do now … Please help!

Thank you!

I found out that bad quality is not caused by UE 4.10.1. After the unistallation of HALArchvizToolkit my project looks as it should.
