Crazyflies loosing poses

[WoodyloveBo]

Hi.

I am researching using multiple Crazyflies using the Crazyswarm API.

Tracking: Optitrack Camera operates at default 300FPS. The number of cameras is 4.
Area 2 x 2 x 2m
It is used in a space where there is no separate external frequency blocking. (If there is a way to check the frequency other than the radio frequency, please let me know.)

Problem: When the hoverswarm script runs, it says "Latency is high!" The phrase appears. Currently, 2 Crazyradios are connected to 4 Crazyflies. When you run the script, the drone takes off, but over time, the drone loses its pose and begins to land.

I was told this was a recalibration issue and I recalibrated it several times. But this wasn't a problem. What should I do additionally?
