pixi-slug — Benchmark

General

Duration per test: ?How long frame times are recorded per scenario. Longer durations produce more stable averages but the full suite takes proportionally longer.

Warm-up frames: ?Number of frames rendered before measurement begins. Lets the GPU pipeline, texture uploads, and JIT settle so early spikes don't skew results.

Canvas: ?Resolution of the PixiJS canvas used during each test. Larger canvases increase GPU fill-rate cost. ×

Fill available area

Pixi Antialiasing: ?Enables MSAA antialiasing on the PixiJS WebGL canvas. May improve edge smoothness for canvas-rendered text but adds GPU overhead.

Background Color: ?Background color of the PixiJS canvas in hex format. The color picker and text field stay in sync.

Resolution: ?Device pixel ratio for the PixiJS renderer. Higher values render at greater pixel density (e.g. 2 for Retina) but increase fill-rate cost proportionally.

GPU Power Preference: ?Hints the browser to prefer a discrete GPU (high-performance) or integrated GPU (low-power). Affects which GPU adapter is selected on multi-GPU systems.

Bezier Smoothness: ?Controls the tessellation quality for PixiJS Graphics bezier curves. Lower values produce more segments (smoother curves). Does not affect Slug rendering which evaluates curves analytically in the shader. Pixi clamps this value between 0 and 1 (inclusive).

Back Buffer: ?When enabled, PixiJS uses a back buffer (offscreen framebuffer) for rendering. Can prevent visual tearing but adds a copy pass per frame.

FPS Limit: ?Cap the frame rate via PixiJS ticker.maxFPS. 0 = uncapped (measure max throughput). Set to 60 or 144 to simulate a vsync-locked display and measure frame-time consistency under a fixed budget.

pixi-slug DISABLED

Supersampling: ?Enable multi-sample antialiasing in the Slug fragment shader. Smoother edges at the cost of extra texture samples per pixel.

Supersample Count: ?Number of supersamples per pixel (2, 4, 8, or 16). Higher counts improve edge quality but increase fragment shader cost.

PIXI.Text (Canvas 2D) DISABLED

Resolution: ?Pixel resolution multiplier for PIXI.Text canvas textures. 2× renders at double resolution for sharper text on high-DPI displays, but doubles texture memory.

PIXI.BitmapText DISABLED

Atlas font size: ?Font size used to rasterize the BitmapFont atlas. Larger atlases look sharper at big sizes but use more texture memory. Text rendered above this size will be scaled up from the atlas.

Benchmarking Tests

Object Count Tiers ?Select which object count tiers to include in multi-object tests (Object Count, Scroll, Mixed Stress, Create/Destroy). Higher counts use more GPU memory and may cause context loss on some hardware.
