Extremely Slow When I Switch To Shade Mode

you have a machine that does not meet v7 system requirements, running an ancient video card driver.

Vendor Name: Intel
Render version: 4.0
Shading Language: 4.00 - Build 10.18.10.4358
Driver Date: 12-21-2015

you may be able to get a little more life out of this machine by updating your intel driver here:
(use the intel automated tool)

you may also work better if you notch down your open gl performance using the open gl slider.

The real answer is: your machine is more than 6 years old… it’s time to retire it and get yourself some up to date equipment. You will be shocked at how much better the new machine with proper graphics cards will run.
