Performance

Tick UI spends CPU and GC budget recording and playing back draw commands each frame. This section covers where that cost lives, what to watch in the profiler, and the patterns that keep frames under budget.

The pages in this section:

• Performance guide: per-frame allocation, draw-command caching, and the call sites that dominate the profile.
• Profiler markers: the marker names, what each one wraps, and how to filter the Unity Profiler.

For the underlying batching model that several markers cover, refer to Drawer and batching.
