The problem was solved by Nvidia, then AMD made it cheap and accessible and not requiring a dedicated hardware module.
For years and years Nvidia increased artificially by up to 150 euros many Gsync screens and for no legitimate reason. Initially there was NO compatibility with free sync at all.
Nvidia wasn’t kindly solving a gamers problem at least to after the first year of release of that tech. They were forcibly selling expensive hardware modules nobody needed or wanted. And long after freesync showed you could do it just as well without this expensive requirements.
This hardware module they insisted on selling wasn’t solving a technical problem but a money one.
I don’t even think anyone was ever able to differentiate between the different qualities of “sync techs”.
IMHO everyone is entirely missing the point pointing their finger at Boeing.
The main issue is the FAA and how it failed to control Boeing. It’s obvious a business will try to sacrifice safety for money. But there should be check and balances. Someone making sure a business doesn’t do that.
The FAA let Boeing supervise itself.
Just to be clear some of the higher up at Boeing are criminals but so is the cop that told him he could police himself.
