Where is the rendering mode in 2.8? I can't find the option where you can see the 3dviewport as the rendered version. Here's the mode I mean: https://ibb.co/GQtHM9L, the left side of the screen.
Shortcut from 2.7x was changed from Shift+Z to switch between Rendered &lt;> Current mode. 

In 2.80 press Z on your keyboard to bring Shading Pie Menu and choose desired mode.
