# Objective - When running any of the stress tests, the refresh rate is currently capped to 60hz because of the `ReactiveLowPower` default used when the window is not in focus. Since stress tests should run as fast as possible (and as such vsync is disabled for all of them), it makes sense to always run them in `Continuous` mode. This is especially useful to avoid capturing non-representative frame times when recording a Tracy frame. ## Solution - Always use the `Continuous` update mode in stress tests.

//! Simple text rendering benchmark.
|
|
//!
|
|
//! Creates a `Text` with a single `TextSection` containing `100_000` glyphs,
|
|
//! and renders it with the UI in a white color and with Text2d in a red color.
|
|
//!
|
|
//! To recompute all text each frame run
|
|
//! `cargo run --example many_glyphs --release recompute-text`
