Basically, it’s using an Oculus Quest 2 to render multiple desktop displays from a laptop into a huge, full-visible-range virtual world:The resolution of these very large displays is surprisingly average—1080p (Reference, Communication) and 4k (Main).

Higher resolutions are available, but this is my calculated trade-off between pixel parity (more on that below), computer performance, and latency. Applications are tuned for readability and crispness, emphasizing information density over anti-aliasing or smoothness.
The article sounds fairly solid, with good tips on how to make a VR headset suitable for constant daily use. -
