This video discusses ways you can measure the performance of your shader and then optimize it so that it runs faster on the GPU. Performance measurement methods include using the built-in Shader Complexity View in Unreal's viewport, monitoring the shader's instruction count, and measuring the actual framerate or GPU millisecond timing required to render your shader. Once you know the performance of your shader, you can optimize it in several ways – including removing unused parts of the shader, restructuring mathematical formulas, merging data from one channel to perform calculations on multiple channels in one single operation, and packing texture maps into a single texture to reduce texture sampling.
