Not massive lag, you only just notice it. However I need to move the lenses in the headset as my eyeballs are working hard to focus when it's on my head but it's fine about 5-10cm back.
What is funny is handing it to someone and watching their response. I should film it for posterity. The dogs make the same motion when they get stuck under a cover or sheet (what, what, where am I, what's going on) 😊
