RenderStats reports the work performed by one render operation.

Fields

ops: u32

ops is the number of replayed operations, including nested lists.

draws: u32

draws is the number of logical draws remaining after culling.

clips: u32

clips is the number of encoded clip operations.

culled: u32

culled is the number of draws skipped because their bounds miss the target.

layers_rendered: u32

layers_rendered is the number of offscreen layers actually rendered.

layers_elided: u32

layers_elided is the number of save layers applied without an offscreen target.

snapshots: u32

snapshots is the number of target-region copies used by destination reads.

backdrops: u32

backdrops is the number of backdrop regions that ran a blur chain.

shared_backdrops: u32

shared_backdrops is the number of backdrop regions that reused a shared blur.

filter_passes: u32

filter_passes is the number of encoded image-filter passes.

text_tiers: [u32; 3]

text_tiers contains glyph-run counts for [bitmap mask, SDF, outline].

glyph_rasters: u32

glyph_rasters is the number of glyphs rasterized after cache misses.

raster_quads: u32

raster_quads is the number of cached display lists drawn as image quads.

raster_fills: u32

raster_fills is the number of display lists rendered into cache textures.

atlas_gcs: u32

atlas_gcs is the number of full glyph-atlas collections.

held_rasters: u32

held_rasters is the number of bitmap or SDF misses served by a resident size.

opaque_reordered: u32

opaque_reordered is the number of opaque draws moved earlier for depth culling.

gpu_ms: f32

gpu_ms is the previous resolved frame’s GPU time in milliseconds.

It is zero until a timestamp resolves or when timestamps are unavailable.

blocks_created: u32

blocks_created is the number of transient upload blocks allocated this frame.

cpu_ms: f32

cpu_ms is total CPU time spent in rendering and submission.

draw_calls: u32

draw_calls is the number of encoded GPU draw commands.

One logical draw may require several commands, while batched glyphs may share one.

render_passes: u32

render_passes is the number of encoded render passes.

pipeline_switches: u32

pipeline_switches is the number of encoded pipeline changes.

vertex_bytes: u64

vertex_bytes is the number of transient vertex bytes uploaded.

uniform_bytes: u64

uniform_bytes is the number of transient uniform bytes uploaded.

plan_ms: f32

plan_ms is the CPU time spent replaying and planning.

encode_ms: f32

encode_ms is the CPU time spent compiling, uploading, encoding, and submitting.
