Love the Metal API but OpenGL ES still performs quite a bit better in my use cases. Somewhat disappointing.

Seems like your Metal usage isn't as optimized perhaps? @warrenm

nah, I think low draw calls with same objects being called w/ different shaders in one frame works better with GL.

Curious about how you translate your shaders and measure relative perf. Feel free to email warren_moore@apple.com

it's actually the CPU why I tested. Haven't tested GPU. But caching logic for buffers ate up any potential gains.
