G-sync vs Adaptive sync/free sync

[Shokyoya]

I dunno if its just me but i clearly remember nvidia discussing this tech back in the days of ATI/3dFX voodoo cards....  the 90's in other words, so am i just olde and feeble minded >< back then i was fairly certain i was against it as all we had then were 60hz monitors and the boost from it did not outweigh the $$$ today however with the 144hz+ becoming more available and HD graphics becoming more popular its finally worthy , but honestly can anyone correct me if im wrong on this ? and if im not would definitely like to see maybe a tech quickie history of it or maybe a comparsion of a then model g-sync to now or something (dunno if they ever made one) CRT's were mainstream then and i think Flat panel CRT's were just starting into exsistence during this development and discussion of the technology, basically i want to know if im olde and feeble remembering something that didnt happen or was the tech just in the planning stages and didnt come about untill 2000+
