If you enable it you will find that the results are very blurry. It's unusable, to me.

I tried that as well with the same results (blurry text). The best approach I found was to install gnome-tweak-tool, and set the font scaling factor to 1.5. Chrome and a lot of other apps scale everything including ui elements by 1.5. The window manager and some other apps don't seem to support this though.
