I wonder what the latency is
- nomel 3y agoFor wireless VR stuff, it's usually 25-40ms range. I believe the encoder hardware is the bottleneck at this point. New Quest 3 is supposed to have better hardware accelerators. I don't notice, with a couple virtual screens.
- jayd16 3y agoThere's also the specifics of how this is grabbing the simulator output and copies it out to the ALVR server. So possibly another frame or two of lag is introduced.
- nomel 3y agoI'm talking desktop screen to VR eye, with desktop streaming. So yes, that, plus simulator latency. I would think input latency should be pretty small.
- trafficante 3y agoQuest 3 will (hopefully) allow for higher bitrates and maybe AV1 support but I don’t see it having a huge impact on overall wireless latency. Decode time on the old SoC is only a few ms with h264 and really the only thing h265 brings to the table on a bandwidth unconstrained local network is 10bit color.

- nomel 3y agoHere are some latency measurements, showing you are correct: https://www.reddit.com/r/oculus/comments/jgfoco/oculus_link_bitrate_settings_latency/ https://www.reddit.com/r/oculus/comments/jgfoco/oculus_link_... I guess my notebook is the bottleneck, at higher bitrates, not the Quest!
- MikusR 3y agoQuest does only Decoding.

- nomel 3y agoOops, meant to write decoder.
- throwawaymobule 3y agoThe headset itself does the reprojection, IIRC. Which is way more noticable than most measures of latency. Never got alvr working, myself.
