But wouldn't that be only necessary if it needed to render real-time graphics at such a scale? If I'm correct, all its doing is playing back videos.
I think it's doing some non-trivial amount of rendering, since it's often syncing graphics with music played live.
Live audio visualization in game engines is definitely a thing ex. https://youtu.be/IZL7VAt97ws?si=H74SwrLZYfsYNTY8
Even if it's just playing back videos, it still should compensate for the distortion of the spherical display. That's a "simple" 3d transformation, but with the amount of pixels, coordinating between the GPUs and some redundancy, it doesn't seem like an excessive amount of computing power. The whole thing is still an impressive excess though...
