I tried using it together with this build of chromium: https://github.com/amd/Chromium-WebCL
but it gives the message: INVALID_CONTEXT and QuotaExceededError on my NVIDIA GTX 770 card.
it seems to crash when calling $CL.context.createCommandQueue() with this error message.
any ideas? Firefox didnt work either. I compiled and installed the plugin, but i get WebCL is undefined.
