Is it really a problem is all competitors have the same performance hit?
Imagine all Olympic athletes were to start competing with an AR headset on, which added 5ms of lag to their vision. Would it be a problem if they were all forced to use it?
No, I don't think it would be a problem, which is why I'm asking the question. Human eye has a 13ms latency according to google and yet it doesn't stop Olympic athletes from existing. I don't see what making the latency 18ms instead of 13ms changes if everybody has the same.
