This is approximate, but often good enough. Specular) makes the view direction normalized per vertex instead of per pixel.

The approxview directive for shaders that use view direction (i.e.

Tweak these for specific situations to make shaders run faster or at least be smaller: However, their default options are tuned to cover a broad number of general cases. More info See in Glossary are great for writing shaders that interact with lighting. Surface Shaders A streamlined way of writing shaders for the Built-in Render Pipeline. Remember that the Alpha Test ( discard) operation often makes your fragment shader slower.

Unity’s built-in options ensure that the driver can generate much better code. Consider using lookup textures as an alternative to complex math calculations if applicable.Īvoid writing your own operations (such as normalize, dot, inversesqrt). Transcendental mathematical functions (such as pow, exp, log, cos, sin, tan) are quite resource-intensive, so avoid using them where possible on low-end hardware. See Data Types and Precision for more details. Most modern GPUs (the ones that can run OpenGL ES 3 or Metal) internally treat fixed and half precision exactly the same. Fixed precision is generally only useful for older mobile GPUs.This is usually faster, and uses less power to do calculations. Mobile GPUs have actual half precision support.This can make testing difficult, as it’s harder to see if half/fixed precision is really enough, so always test your shaders on the target device for accurate results.

All modern desktop GPUs will always compute everything in full float precision, so float/half/fixed end up being exactly the same underneath.In practice, exactly which number type you should use for depends on the platform and the GPU. For very simple operations on texture data, use fixed precision.For everything else (vectors, HDR colors, etc.), start with half precision.For world space positions and texture coordinates, use float precision.This is especially important on lower-end hardware. When writing shaders in Cg/HLSL, there are three basic number types: float, half and fixed (see Data Types and Precision).įor good performance, always use the lowest precision that is possible. More info See in Glossary code, or move them out of shaders completely and set the values in a script.

Where possible, move computations out of the pixel shader code into the the vertex shader A program that runs on each vertex of a 3D model when the model is being rendered. Usually there are many more pixels rendered (and subsequently more pixel shader executions) than there are vertices (vertex shader executions), and more vertices than objects being rendered. The frequency of computations will also impact the performance of your game. More info See in Glossary rendered on screen. Pixel lighting is calculated at every screen pixel. Pixel size depends on your screen resolution. For example, supporting color per material is nice to make a shader more flexible, but if you always leave that color set to white then useless computations are performed for each vertex or pixel The smallest unit in a computer image. The more computations and processing your shader code needs to do, the more it will impact the performance of your game. This page contains information on optimizing your shaders for runtime performance. More info See in Glossary have “mobile” equivalents that are much faster, but have some limitations or approximations. Use them with materials to determine the appearance of your scene.

For example, some built-in Shader objects An instance of the Shader class, a Shader object is container for shader programs and GPU instructions, and information that tells Unity how to use them. It’s recommended that you manually optimize your shaders to reduce calculations and texture reads, in order to get good performance across low-end GPU machines. GPU performance on mobile platforms and low-end PCs is likely to be much lower than on your development machine. The same is true even on a single platform a fast GPU is dozens of times faster than a slow integrated GPU. More info See in Glossary than a low-end mobile GPU.

Different platforms have vastly different performance capabilities a high-end PC GPU can handle much more in terms of graphics and shaders A program that runs on the GPU.
