That´s it.
WIN 10 share connection isn´t working(most cases) if You try to play 4k videos - I can confirm it´s not working
You have to attach local HDD/SSD or an NAS using NFS protocol - I can confirm it works not only some samples
Am I missing somthing her??? I have no problem playing 4k from windows sharer. I can even play the jellyfish demo at 140mbps 4k 10bit hdr.
