Transitioning from WebGL to WebGPU for Faster Graphics

For over a decade, WebGL has been the sole standard for hardware-accelerated 3D graphics in the browser. Built on OpenGL ES, it exposed a state-machine API that worked well for its era but imposed significant CPU overhead and lacked direct access to modern GPU features. Enter WebGPU — a next-generation graphics and compute API designed from the ground up for modern GPU architectures.

Optimizing Browser Rendering Pipelines (Critical Path)

Introduction

The Critical Rendering Path (CRP) is the sequence of steps the browser performs to convert HTML, CSS, and JavaScript into visible pixels on the screen. Optimizing this pipeline directly impacts First Contentful Paint (FCP) and Largest Contentful Paint (LCP). This article breaks down each CRP stage — DOM construction, CSSOM construction, render tree, layout, paint, and composite — and provides actionable optimization strategies.

Stage 1: DOM Construction

When the browser receives HTML bytes, it:
