Cannot see dynamic shadow in editor


I wonder, I created brand new tutorial First person shooter (blueprints) project. I navigate the viewport and simulate the game in it but I don’t see any dynamic shadows.

“Show / Light components / Dynamic shadow” checkmark is on by default.

Though, if I run game at standalone window - I see all the fancy effects, dynamic shadows, motion blur, et.c.
Just in case, this is GeForce GTX 750 on Windows 7.

Up, please

Found. At UE4, at Viewport, click Show - select shader quality to Epic.
