Oculus Quest 2 builders can now allow a brand new ‘Excessive Frequency Hand Monitoring’ mode of their apps, rising the monitoring price from 30 Hz to 60 Hz.
Fb claims the mode will increase hand monitoring high quality, in addition to lowering its end-to-end latency by 10%. Its inner ‘Strike Group’ enabled the brand new mode within the Tiny Castles demo and reported the next outcomes:
“In Tiny Castles, we noticed that top frequency hand monitoring ends in a slight discount in perceived latency but in addition considerably improved monitoring high quality throughout quick hand actions. There have been no perceived modifications relating to jitter and occlusion.“
Nonetheless, Fb says there’s a “slight enhance in jitter” for low mild situations, which it plans to repair in a future software program replace.
Builders can allow Excessive Frequency Hand Monitoring by including this line to the Android manifest:
Oculus apps can set the CPU & GPU clock price – to not a particular worth however to five predefined ranges (Zero-Four). This lets builders steadiness efficiency and battery life.
Excessive Frequency Hand Monitoring requires extra background computing energy to course of the cameras at double the traditional price. Fb says this may trigger headset overheating (resulting in a sudden shutdown), so to keep away from this, apps utilizing the function shall be capped to CPU & GPU Degree 2.
Meaning whereas enabling this function is technically a one-line change, really making it work in actual apps may require important optimization work.
Fb says that going ahead, even apps utilizing low frequency Hand Monitoring shall be restricted to CPU & GPU Degree three, to keep away from overheating.
