How many milliseconds of latency are generally tolerable in VR before motion

Developers generally target keeping motion-to-photon latency under 20 milliseconds in virtual reality to maintain immersion and prevent motion sickness ^[1][2]. When display panels operate at 90Hz, they create a 13-millisecond delay that most users find comfortable, establishing an industry benchmark ^[3]. Delays exceeding this threshold risk causing discomfort and nausea as the brain detects a mismatch between physical movement and visual feedback ^[4].Would you also like to know which hardware components most influence motion-to-photon latency in virtual reality?
