Capping framerate at or near the refresh rate with V-Sync off tends to make tearing the most noticeable for some reason - capping a little down can work but I usually find (though sometimes harder to achieve) that running a lot higher framerate than the refresh rate i.e. 100+ on a 60Hz panel gives the least perceived tearing - I used to run SLI setups partly for that reason.
Thats why i play OW currently at 260+ fps( almost everything set to low @1440p) on my 144hz display, i prefer it due to the feel of the mouse over gsynced 144hz. Did the same a lot back when i was running a 60 and 75hz ultrawide. Worked great.. just pump out so many frames that the top and bottom of the tear gets closer and a lot less noticeable.
