I asked this in the iPhone forum, but thought I'd give it a chance here instead. It seems Unity is setting precision specifiers automatically in GLSL ES shaders with no way of overriding (VERTEX_P as higp, FRAGMENT_P as mediump). This makes it really hard to squeeze out that extra bit of performance (since there is a 2x …
