Struct FrameStats 

Source 
pub struct FrameStats {
    pub frames: usize,
    pub fps: f32,
    pub avg_ms: f32,
    pub p50_ms: f32,
    pub p95_ms: f32,
    pub p99_ms: f32,
    pub max_ms: f32,

}
Expand description

Frame-time statistics over the last few seconds, from Ctx::frame_stats. All times in milliseconds; the CPU and GPU parts are averages.

What limits the frame rate: if gpu_ms is close to avg_ms, the GPU; if systems_ms + render_cpu_ms is, the CPU; if display_wait_ms is large, the display (vsync), and there is room to spare.

Fields§

§frames: usize

Frames the statistics cover.

§fps: f32

Frames per second, from the average frame time.

§avg_ms: f32

Average time from one frame to the next.

§p50_ms: f32

Median frame time.

§p95_ms: f32

95th percentile frame time: 1 frame in 20 is slower.

§p99_ms: f32

99th percentile frame time: the stutters.

§max_ms: f32

The slowest frame.

§systems_ms: f32

CPU time in systems (game logic, physics, collecting what to draw).

§render_cpu_ms: f32

CPU time spent drawing: preparing GPU data, recording and submitting.

§display_wait_ms: f32

Time waiting for the display to take a frame (idle, not work).

§gpu_ms: Option<f32>

GPU time of a frame, if the GPU can measure it.
