Video Playing high-res 360 3D video with VideoPlayer

Has anyone managed to get a high res 360 3d video playing in Unity without 3rd party plugins? Trying to use a video from Vuze Camera (4096x4096, mpeg4 h264 encoded) and play it on skybox material results in stutter even on a high end rig (it's not the app itself lagging, but the video). Lowering quality is not an option - the previous iteration of app used lower quality videos and it was ugly AF. So, are there options or AVPro is necessary here?
