Update 9/30/18 3:22 AM: After further research and the collection of more high-speed camera footage from our G-Sync displays, I believe the tear-free gameplay we're experiencing on our FreeSync displays in combination with GeForces is a consequence of Windows 10's Desktop Window Manager adding some form of Vsync to the proceedings when games are in borderless windowed mode, rather than any form of VESA Adapative-Sync being engaged with our GeForce cards. Pending a response from Nvidia as to just what we're experiencing, I'd warn against drawing any conclusions from our observations at this time and sincerely apologize for any misleading conclusions we've presented in our original article. The original piece continues below for posterity.
