does 4:4:4 decoding really cost more silicon when a hardware decoder can do 8K 4:2:0 and 4:4:4 is limited to 4k in this case?
BTW. freesync and gsync screen work out of the box with pretty old hardware and even entry level screens have often support for it (mostly useless like TVs).
and player seem to support it too. a high end gaming PC is clearly not needed.
