Do you have WinXP? I think WebGL is disabled by default in XP because of instability (at least in Chrome).

I just ran it on Chrome 10.0.648.205 on Ubuntu 10.10 and I get the same error.

I don't think any browser supports WebGL on Ubuntu yet.

edit: On Ubuntu, first close all chrome windows. Then start chrome with the command-line option "--ignore-gpu-blacklist" and it works.

I think that might have something to do with the underlying GPU capabilities of your computer, happened to me as well with Chrome 12!

Your browser is not checking your graphics card.

It's an error in the version detection.

This is why we should be checking for capabilities/features and not version. And part of this is reporting the correct, helpful error message when the capability isn't there, and not just say they have the wrong version.

I still have this problem with 64 bit flash on Linux, which adobe has decided to use a different format version string for.

It is checking for capabilities and not version: try { gl = canvas.getContext( "experimental-webgl") ; gl.viewportWidth = docWidth; gl.viewportHeight = docHeight; } catch(e) { } if (!gl) { alert("This website requires WebGL. Try running Chrome 9+ or Firefox 4+"); }

Yep, it's not the Chrome version. It works fine for me using Chrome 10.0.648.204.

I'm trying with FF4 and Chrome 11 with a GeForce 9600 GT and it still gives me the error message.

GPU acceleration is off by default in Chrome 10 on Windows XP.

It worked for me when I started Chrome with: chrome.exe --enable-webgl --ignore-gpu-blacklist

Works great here on Firefox 4, so maybe a problem with your graphics card drivers? Do any other WebGL demos work?

Mozilla maintains a wiki on blocked video drivers and how to force enable them for each os/platform.

I had to go to about:config and force WebGL enabled on Firefox 4 on XP with a Geforce 8800GT.
