Browser support for WebGL

Check caniuse.com/webgl to see whether your browser supports WebGL.

Enabling WebGL

If your browser supports WebGL, follow these instructions to enable information technology:

Chrome

First, enable hardware dispatch:

• Go to chrome://settings
• Click the Advanced ▼ button at the lesser of the folio
• In the Organisation section, ensure the Use hardware acceleration when available checkbox is checked (y'all'll need to relaunch Chrome for whatever changes to take effect)

And then enable WebGL:

• Go to chrome://flags
• Ensure that Disable WebGL is not activated (y'all'll need to relaunch Chrome for whatsoever changes to take effect)

• In newer versions, this option of Disable WebGL volition not be available, you will instead take to search for WebGL 2.0 (or some different version) that looks like this:

  

  Here you will have to change Default to Enabled in the driblet down.

• [Attempt this if above doesn't work] Enable - Override software rendering list

So inspect the status of WebGL:

• Go to chrome://gpu
• Audit the WebGL item in the Graphics Characteristic Condition list. The status will exist one of the following:
  • Hardware accelerated — WebGL is enabled and hardware-accelerated (running on the graphics menu).
  • Software simply, hardware acceleration unavailable — WebGL is enabled, merely running in software. See here for more info: "For software rendering of WebGL, Chrome uses SwiftShader, a software GL rasterizer."
  • Unavailable — WebGL is non available in hardware or software.

If the status is not "Hardware accelerated", then the Problems Detected list (below the the Graphics Feature Status list) may explain why hardware acceleration is unavailable.

If your graphics carte du jour/drivers are blacklisted, you can override the blacklist. Warning: this is non recommended! (see blacklists note below). To override the blacklist:

• Go to chrome://flags
• Activate the Override software rendering list setting (you'll demand to relaunch Chrome for any changes to have effect)

For more than information, see: Chrome Help: WebGL and 3D graphics.

Firefox

First, enable WebGL:

• Go to about:config
• Search for webgl.disabled
• Ensure that its value is faux (any changes take effect immediately without relaunching Firefox)

Then inspect the status of WebGL:

• Become to about:back up
• Inspect the WebGL Renderer row in the Graphics table:
  • If the status contains a graphics card manufacturer, model and driver (eg: "NVIDIA Corporation -- NVIDIA GeForce GT 650M OpenGL Engine"), and then WebGL is enabled.
  • If the status is something like "Blocked for your graphics card considering of unresolved driver issues" or "Blocked for your graphics commuter version", then your graphics card/driver is blacklisted.

If your graphics card/drivers are blacklisted, you tin override the blacklist. Alert: this is not recommended! (see blacklists note beneath). To override the blacklist:

• Go to near:config
• Search for webgl.forcefulness-enabled
• Set information technology to true

(Similar Chrome, Firefox has a Use hardware acceleration when available checkbox, in Preferences > Avant-garde > Full general > Browsing. However, different Chrome, Firefox does not require this checkbox to be checked for WebGL to work.)

Safari

• Go to Safari'due south Preferences
• Select the Advanced tab
• Ensure that the Bear witness Develop menu in carte du jour bar checkbox is checked
• In Safari's Develop bill of fare, select Experimental Features sub-carte and ensure that WebGL ii.0 is checked

Notes

Upgrading graphics drivers

If your graphics drivers are too erstwhile to back up WebGL, you lot may be able to upgrade them.

More information is available hither:

• Chrome: Graphics aren't showing properly
• Firefox: Upgrade your graphics drivers

Blacklists

Certain graphics cards and drivers are blacklisted by some browsers, because they are known to contain serious bugs or cause crashes. In very severe cases, these can even cause the entire computer to freeze! For instance, this issue causes certain Mac computers to freeze and require restarting.

Many browsers have an pick to override the blacklist (ie: attempt to use the blacklisted features, despite the risks). This is non recommended! You should only override the blacklist if you lot empathise and accept the risks.

More information is available here:

• WebGL Blacklists
• Chrome: Blacklisted GPU features
• Chrome: GPU driver bug list
• Firefox: Blocked graphics drivers
