So ive just noticed that gsync only works in windowed mode, and doesnt work in fullscreen mode. its not a majooor issue as you can window borderless, however its not ideal.
i wanted to know if anyone else has the problem, and if dice are aware of the issue? as it only happens on bf5. i was talking to some people in game and they said they had the same issue and it was a dell monitor..
rog swift 144hz
edit. right after a test it doesnt work on battlefield 4 either unless its in borderless mode! which is funny as i always said the smoothness didnt seem to match the fps i had especially with gsync! unbelievable! again i just brushed it off as me being too analytical and looking to hard at my screen.
