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 …

OpenGL ES shader precision modifiers (lowp, mediump, highp)

WebThis specification is based on the work of those who contributed to version 1.10 of the OpenGL Language Specification, the OpenGL ES 2.0 Language Specification, version 1.10, and the following contributors to this version: Nick Burns Chris Dodd Michael Gold Jeff Juliano Jon Leech Bill Licea-Kane Barthold Lichtenbelt Benjamin Lipchak Ian ... WebOpenGL ES exposes a precision modifier that allows control of the desired precision for different data types: highp, mediump and lowp. When used on floats, the mapping is typically as follows: highp - generally 32-bits (on some devices 24-bits in fragment shader) mediump - generally 16-bits lowp - generally 11-bits incompatibility\\u0027s 1o
