Package Exports

detect-gpu

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (detect-gpu) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Detect GPU

Classify GPU's based on their benchmark score in order to provide an adaptive experience.

Demo

Live demo

Installation

Make sure you have Node.js installed.

 $ npm install detect-gpu

Usage

detect-gpu uses benchmarking scores in order to determine what tier should be assigned to the user's GPU. If no WebGLContext can be created or the GPU is blacklisted TIER_0 is assigned. One should provide a HTML fallback page that a user should be redirected to.

By default are all GPU's that have met these preconditions classified as TIER_1. Using user agent detection a distinction is made between mobile (mobile and tablet) prefixed using GPU_MOBILE_ and desktop devices prefixed with GPU_DESKTOP_. Both are then followed by TIER_N where N is the tier number.

In order to keep up to date with new GPU's coming out detect-gpu splits the benchmarking scores in 4 tiers based on rough estimates of the market share.

By default detect-gpu assumes 0% of the lowest scores to be insufficient to run the experience and is assigned TIER_0. 50% of the GPU's are considered good enough to run the experience and are assigned TIER_1. 30% of the GPU's are considered powerful and are classified as TIER_2. The last 20% of the GPU's are considered to be very powerful, are assigned TIER_3, and can run the experience with all bells and whistles.

You can tweak these percentages when registering the application as shown below:

import { getGPUTier } from 'detect-gpu';

const GPUTier = getGPUTier({
  glContext?: gl, // Optionally pass in a WebGL context to avoid creating a temporary one internally
  mobileBenchmarkPercentages?: [0, 50, 30, 20], // (Default) [TIER_0, TIER_1, TIER_2, TIER_3]
  desktopBenchmarkPercentages?: [0, 50, 30, 20], // (Default) [TIER_0, TIER_1, TIER_2, TIER_3]
  forceRendererString?: 'Apple A11 GPU', // (Development) Force a certain renderer string
  forceMobile?: true, // (Development) Force the use of mobile benchmarking scores
});

detect-gpu uses both mobile and desktop benchmarking scores from https://www.notebookcheck.net/.

The unmasked renderers have been gathered using the analytics script that one can find in scripts/analytics_embed.js.
