If your web build still rides legacy assumptions, you are heading into a compatibility and performance bottleneck at the same time. Browser players feel every hitch, and they bounce fast.
This module maps the real WebGL to WebGPU transition path in Unity: what improves, what is still experimental, and how to ship fallbacks without chaos. You get practical guidance on APIs, shader flow, browser support, and platform constraints.
The proof frame is specific: Unity 6 raises desktop WebAssembly heap from 2 GB to 4 GB, adds SIMD and multithreaded runtime gains, and unlocks compute-shader workflows that WebGL cannot run natively. At the same time, you get hard limits and decision criteria, including URP-only status, browser variance, and why WebGPU-first with WebGL2 fallback is the safe production posture right now.
Your next step is concrete: set WebGPU first and WebGL2 second in Graphics APIs, run the same scene on Chrome and Edge, then profile CPU, GPU, and memory behavior before committing feature paths.
CEO/Producer translation: you future-proof web delivery while controlling launch risk, instead of betting everything on one unstable graphics path.
Unlock this module and adopt the full WebGPU migration workflow with measurable checks and fallback strategy.
