Hi there,
Thanks for your feedback and sorry for the inconvenience.
You can directly watch your 8K videos on your pc using SKYBOX. Please unplug your Oculus link cable and use SKYBOX Quest version to see if the playback gets better.
If you connect your headset to your pc with Oculus link cable, then you are using SKYBOX Rift version, which hasn't been updated for a long time.
Hope that helps. Let us know if you need further help. We are always happy to help.
Best regards,
Lucy
