Help getting Overwatch to run at 120 frames

Hey!
I was hoping to see if anyone had advice on how to get Overwatch to run at 120 frames on a GTX 1660 Super and an AMD Ryzen 5 3600. I tried lowering my graphics settings, but oddly enough it lowered my framerate from 85 to 74. If any one has any help for this, that would be great!

Greetings, I have a full detailed guide here which helps provide some key insights to maximizing your performance in Overwatch:

Make sure your resolution scale wasn’t set to over 100% when you selected “Low” settings.

Also make sure you have Vsync off. If you experience screen tearing, turn on Gsync for a high refresh rate monitor.

Thanks for the help!
