As Fast Sync was recently given support on older cards I have been using it on my GTX 960 for the last week or two and my word what a difference it makes when you've been limited to either vsync or no vsync for years on end. Setting the render ahead setting to 3 in the control panel also has helped matters and now all my games play with no tearing whatsoever and hit well above the 60fps ceiling I was so used to without any kind of overheating or issue.
Tis wonderful I tell you, wonderful I say.
Her face is tired. Leave her be ffs.
