4.7. questions

What happend with u4 4.7?
Why does my computer lag when I try to move something out of my content browser to the scene?
It just freezes everything and it’s impossible to do anything.
As far as I understood it compiles shaders of my content, but it’s absolutely annoying.
In 4.6. everything worked perfectly, but now… what happened to it?

Also I’ve got really inconveniened interface, when I open something (bp, material or just viewer of my model) it openes it in a fullscreen window. How to change it? I want to open it in a windowed mode.

Also I lost a destructable mode from my static mesh preferences. Where is it now?


These are only my main questions, btw 4.7. became really inconvenient, comparing with previous versions of the engine.
