Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
The ANGLE_timer_query has been deprecated from the ES specification and has 
been replaced by EXT_disjoint_timer_query.

EXT_disjoint_timer query is desperately needed. Measuring performance by way of 
FPS is completely unusable, as it mostly just boils down to 3 answers, 15fps, 
30fps or 60fps. Programmers can't measure their WebGL programs, and hence they 
cannot optimize them. This is extremely bad.

I'd like to add this to my plate of things to tackle. If someone urgently needs 
this and wants to work on it, feel free to snag.
