The Short Version
Apple announced LGTM, a rendering framework that cuts the computing cost of sharp 3D graphics on VR and AR headsets.
Apple's LGTM framework does one specific thing: it makes rendering sharp 3D graphics cheaper to compute, so a headset can show better visuals without burning through its battery or needing a hardware upgrade. That directly removes two of the biggest complaints about current headsets, cost and battery life, without asking anyone to buy new gear. The catch is that no shipping date or device list is confirmed yet.
