Troubleshoot WebGL issues in the Corsmed MRI Simulator

The Corsmed MRI Simulator relies on your browser’s ability to render advanced 2D and 3D graphics using WebGL. While most modern browsers support WebGL, certain configurations may cause crashes, poor performance, or unexpected behavior.

What is WebGL?

WebGL is a web technology that allows websites to display interactive 2D and 3D graphics directly in your browser without installing additional software. It runs inside standard web pages and can use your computer’s graphics hardware (GPU) to improve performance.

Common WebGL issues

You may experience WebGL-related problems if any of the following apply:

• Your browser does not support WebGL

  • Older, misconfigured, or outdated browsers may not fully support WebGL.

• WebGL is disabled in browser settings

  • Hardware acceleration may be turned off, or WebGL may be manually disabled.

• Graphics driver is outdated or incompatible
  • Outdated or incompatible drivers can prevent WebGL from functioning correctly.
• Limited hardware specifications
  • Older or low-spec devices or systems without dedicated GPUs may struggle with WebGL.
    
• Operating system interference
  • Missing OS updates or certain OS configurations can interfere with WebGL.
• Browser blacklists
  • Some browsers disable WebGL on specific graphics cards or drivers known to cause issues (for example, Internet Explorer 11).

How to fix WebGL issues

Google Chrome

1. Ensure Chrome is updated to the latest version.
2. Enable hardware acceleration:
   • Go to chrome://settings/system
   • Turn on Use hardware acceleration when available
   • Restart Chrome
3. Check WebGL status:
   • Visit chrome://gpu
   • Look for WebGL and WebGL2 under Hardware accelerated

If WebGL is not accelerated (only recommended if you understand the risks):

• Visit chrome://flags
• Enable Override software rendering list
• Relaunch Chrome

If issues persist, update your graphics drivers.

Mozilla Firefox

1. Update Firefox to the latest version.
2. Check WebGL settings:
   • Visit about:config
   • Ensure webgl.disabled is set to false
3. Check WebGL status:
   • Visit about:support
   • Under Graphics, look for WebGL Renderer

If WebGL is blocked (not recommended unless necessary):

• Set webgl.force-enabled to true in about:config

Microsoft Edge

1. Update Edge to the latest version.
2. Enable hardware acceleration:
   • Go to edge://settings/system
   • Turn on Use hardware acceleration when available
   • Restart Edge
3. Check WebGL status:
   • Visit edge://gpu
4. Update your graphics drivers if needed.

Safari (macOS)

1. Update both Safari and macOS to the latest versions.
2. Enable WebGL:
   • Go to Safari → Settings → Advanced
   • Enable Show Develop menu
3. From the Develop menu:
   • Select Experimental Features
   • Ensure WebGL 2.0 is enabled
