High res camera latency
-
voxl-inspect-cam -a shows that the hires_down_large_color latency is >900ms. What is the cause of the latency and can it be reduced?
Thanks!

As an update, I was able to get the latency down to about 50-60ms by making the following changes to /etc/modalai/voxl-camera-server.conf. Are there any other optimizations I can make?
