Hello everyone. I'm having difficulty watching 5k videos form hard drive (5400x2700-60fps). In all players. In Rift and in desktop. It freezes, spikes, the image lags behind the sound. 4k videos plays good. 5k videos form youtube plays good too. I recently upgraded the system from i7-4820K to i5-7400 and I thought that this would solve the problem. But that did not happen, it still lags. Tell me, please, what part in my system does not meet the requirements of 5k?
Z170M-E D3 motherboard, i5-7400, gtx980, ddr3 16Gb, 6Gb/s HDD, win10.
Used players: Whirligig, VLC, WMP, MPC.
