WebGPU Pooled Effects

Interactive Three.js WebGPU/TSL demo for WebGPU Pooled Effects, with 7 scenarios, 7 mechanisms, and 3 quality tiers and evidence-gated validation.

Evidence status: The implementation is available for technical review, but its native-WebGPU runtime and evidence gates remain incomplete.

Readiness & remaining fixes 4

Declared evidence work remains. Overall implementation status does not establish individual runtime or performance claims.

P0Define and measure the target performance contract

The ultra, high, medium tiers have no accepted frame target. Record named device/browser/GPU, viewport, DPR, sustained CPU/GPU/presentation p50 and p95, deadline misses, memory, and settled quality. Submission time is not GPU timing.

P2Close tier-specific acceptance

Validate and promote ultra, high, medium as independent visual and performance contracts without crossing their protected invariants.
