Automatic quality detection - test_performance(callback)

I am trying to use the test_performance(callback) function within the sdk but unfortunately I am only getting a response in the chrome browser.

Later Internet explorer (webgl enabled) browsers, safari and firefox always return a value of 0

Chrome normally returns a value of 2 - 60 gb/s.

Is this functionality limited to specific browser / webkit types?

Hi!
For now this feature is limited to Chrome and Chrome-based browsers as it requires EXT_disjoint_timer_query WebGL extension. In the future it will be available in other browsers as well, thus consider it experimental
