RenderSystem

Struct RenderSystem

pub struct RenderSystem {
    pub draw_calls: u32,
    pub visible: u32,
    pub quality: Quality,
    /* private fields */
}

Expand description

Frame submission system: cull + count what would be drawn, then batch according to the current Quality.

Fields§

§draw_calls: u32§visible: u32§quality: Quality

Current tier; starts at High and moves only through RenderSystem::observe_frame.

Implementations§

impl RenderSystem

pub fn new() -> Self

pub fn observe_frame(&mut self, avg_ms: f32, budget_ms: f32)

Feed the governor one frame’s average time (from Scheduler::avg_frame_ms) and the budget it is graded against. Sustained overruns step quality down; sustained runs with real headroom step it back up. Everything between resets both streaks — the middle of the budget is where we want to stay.
