Enabling Facial Expressions on Networked Avatars
Hi all! I'm looking to enable face tracking for a multiplayer game I'm currently developing where each avatar is network instantiated. The current documentation explains how to set it up for local avatars. Is there any documentation available for networked instantiated avatars?
Quest Link USB3 transmit latency significantly higher on Quest Pro
Hey all, I recently got a Quest Pro (and shortly after, a Quest 2) and being the stubborn person that I am, decided to try writing an OpenXR driver for Quest Link to use on macOS and Linux, since Meta does not currently support these platforms (nor do I expect them to any time soon lol). However while writing my own driver, I noticed that the Quest Pro consistently had worse performance. Looking further, I found that with the exact same resolution, encoding settings, etc, Quest 2's USB transmit is a stable 0.5ms, whereas the Quest Pro often crosses the 1ms transmit time. Quest 2: INFO [comp_ql_calc_frame_pacing] Avg: tx 0.575194ms, encode 18.336222ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.479831ms, encode 18.421983ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.482888ms, encode 18.347163ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.480982ms, encode 18.464094ms Quest Pro: INFO [comp_ql_calc_frame_pacing] Avg: tx 1.075382ms, encode 12.934615ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.710841ms, encode 10.299981ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.850958ms, encode 10.371938ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.645109ms, encode 10.543258ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.592482ms, encode 10.271824ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.770167ms, encode 10.140699ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.911711ms, encode 10.275272ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.556561ms, encode 10.065738ms Both devices are on v47, and `libusb_get_device_speed` returns `LIBUSB_SPEED_SUPER` for both headsets, so in theory they should be operating at 5000Mbit/s. It's worth noting that I'm including the cap'n proto preamble packets, so that's 0.4ms Quest 2/1ms Quest Pro across 3-4 packets (segment sizes + cap'n proto + optional csd + idr/coded slices).
