Per John Carmack 'Latency Mitigation Strategies' (2013) and Abrash GDC 2013, the latency budget target for comfortable VR is approximately which?
A≤ 1 s motion-to-photon
B≤ 20 ms motion-to-photon
C≤ 500 ms motion-to-photon
D≤ 200 ms motion-to-photon
Answer & Solution
Correct answer: B. ≤ 20 ms motion-to-photon
Carmack 2013 + Abrash 2014: motion-to-photon ≤ 20 ms target for comfort. The earlier 50 ms threshold causes noticeable lag and discomfort.
