3D 360 video viewing - laggs

Hello!

We made 3D 360 video 4Kx4K video. We stiched, but we do have some problems viewing it. I used several players but they all seem to be a little bit slow. We have got realy fast PC (Core i7-5930K, 16GB DDR4, GF 770, SSD), but we get some laggs playing the video. All 12 cores CPU are 100% busy, GPU is not used at all.

Do I have any solution to make video faster? Perhaps we should use other codec?

Does anybody has any solution / idea?

    I'm struggeling to get 4Kx4K videos to play at reasonable speeds as well. The best result I had yet was using ffmpeg with the x264 codec to convert the videos.
    At the moment I use parameters like this for encoding ( for image sequences ):

    ffmpeg.exe -f image2 -start_number 1001 -i "input.%04d.jpg"  -r 30 -y -c:v libx264 -preset veryslow -tune fastdecode -tune zerolatency -pix_fmt yuvj420p -b:v 16M  "output.mp4"


    And LiveViewRift + K-Lite codec pack for playback. It works more or less but doesn't play in realtime either :(

    If you are using the LAV video decoder ( from the K-Lite pack ) you could also try to enable the hardware acceleration
