# Performance

* Proximity checks throttled when none visible (`Config.ProximityCheckInterval`)
* \~30fps screen updates only while visible (`Config.ScreenUpdateInterval`)
* NUI messages send only deltas (position changes)
* UI unmounts entirely when idle (zero React overhead)

Tested with many holograms active without hitching.

## Troubleshooting

### Nothing appears in-game

* Are you within `radius` of the coords?
* Is `ensure SickHolograms` in `server.cfg` and the UI built?
* Check F8 for NUI errors

### Emojis look odd

* Try Windows emoji or Noto Color Emoji on Linux build hosts.
