alpha version of opera 12 with full hardware acceleration and WebGL support released and available for download from the Opera website. We’ve decided not to review it now, but we’ve covered the Opera 11.50 build with webGL and hardware acceleration in the past. Pretty clear things from Opera, this release uses the GPU to the fullest extent possible to render the UI, the full webpage, and webGL.
Check whether your graphics card supports Opera 12 or not
Opera confirm this version of Opera currently supports OpenGL and DirectX 9/10 on Windows is still in progress. Like other browsers Opera Blocklist Graphics Cards and Drivers that cause systems to fail. These block lists located in the Program FilesOpera NextExtra directory.
As we said, Opera automatically locks if the old graphics card is detected by checking its blacklist, so Opera goes back to Vega backend software to render pages. you can check GPU Status for Opera visiting Opera: GPU in your browser. If the Vega Backend software appears, your graphics card is locked and confirmed.
Disabling Opera 12 and WebGL Hardware Acceleration
If you are using a computer with an old graphics card, you may experience BSOD, Opera recommends that you update your drivers. Opera 12 alpha is still a trial version, still buggy, here is how to disable WebGL and hardware acceleration in Opera browser if you have problems.
To disable hardware acceleration, visit “opera:config#UserPrefs|EnableHardwareAcceleration” (without quotes) in Opera and set its value to 0. (You can force opera 12 to support HA regardless of the locked card by setting the value of the mentioned setting to 2).
To disable WebGL, visit “opera:config#UserPrefs|EnableWebGL” (without quotes) and set its value to 0. (You can force Opera to support WebGL by setting the aforementioned configuration value to 2 as well.
You need to restart the Opera browser for the changes to take effect.
PS. We have disabled HA and WebGL for Opera 12 as we are using the system with old graphics card.
