FirmBark well this tech (things like gaussian splatting, nurbs, etc) is moving crazy fast but deconding volumetric vr videos still requires a lot of processing power now.
Bet we could run the 4k sbs equivalent (quality wise) on a 4090 or something but for sure not on a quest. It's gonna get there though and probabily sooner then later. This tech is moving very fast probably because it's very valuable for Ai training.
