Same for adaptive sync. Gsync was first to market by a country mile, the adaptive sync standard wasn’t even approved until like 6 months after the first gsync stuff showed up and if nvidia hadn’t gone first it would have taken much longer if it happened at all.

Freesync wasn’t really market-ready until at least 2015 and the early products were mostly junk, it’s not until the gsync compatible program that any vendors really cared about LFC or flickering issues.
