Stumbled into this thread as I jumped onto the ‘G-Sync compatible’ bandwagon just recently. I can easily say that so far most of the games I play behave SIGNIFICANTLY better with V-Sync on in-game and left to app preference in NVCP. Don’t ask me why. I even refunded Metro Exodus before discovering this, as it was running like crap. Wish I had known better. Gonna try HAGS off and see if I can get even better results, but so far I’m sorry to say that Blurbusters’ suggested G-Sync settings have been a disaster for me performance-wise.
