//! Render Queue benchmark (#3335): a 1080p 32 bpc job on the GPU, the CPU or the measured choice.
|
||||
//!
|
||||
//! `cargo run --release -p effectcraft-ui-egui --example rq_bench -- [options]`
|
||||
//!
|
||||
//! It builds a comp like a compositing shot: a 1920 × 1080 OpenEXR sequence (float RGBA with a
|
||||
//! Cryptomatte ID channel and manifest, generated once into `target/rq-bench/media`, no
|
||||
//! committed media) under Gaussian Blur, Curves and the Cryptomatte effect and a moving
|
||||
//! translucent solid, at 32 bpc. It queues the comp twice (the second item shows a warm start) and
|
||||
//! renders the queue as the app does, printing each item's milliseconds per frame and a hash of
|
||||
//! the written pixels (equal hashes: identical output).
|
||||
//!
|
||||
//! Options: `--renderer gpu|cpu` (the project's renderer, default gpu; with gpu the Render
|
||||
//! Queue measures both unless `EFFECTCRAFT_RQ_RENDERER` says otherwise), `--frames N` (default
|
||||
//! 60), `--format png|exr|tiff` (default png), `--out DIR` (default `target/rq-bench/out`).
